The DA14580 contains the following internal blocks: 4.1 ARM CORTEXM0 CPU The Cortex-M0 processor is a 32-bit Reduced Instruction Set Computing (RISC) processor with a von Neumann architecture (single bus interface). It uses an instruction set called Thumb, which was first supported in the ARM7TDMI processor; however, several newer instructions from the ARMv6 architecture and a few instructions from the Thumb-2 technology are also included. Thumb-2 technology extended the previous Thumb instruction set to allow all operations to be carried out in one CPU state. The instruction set in Thumb-2 includes both 16-bit and 32-bit instructions; most instructions generated by the C compiler use the 16-bit instructions, and the 32-bit instructions are used when the 16-bit version cannot carry out the required operations. This results in high code density and avoids the overhead of switching between two instruction sets. In total, the Cortex-M0 processor supports only 56 base instructions, although some instructions can have more than one form. Although the instruction set is small, the Cortex-M0 processor is highly capable because the Thumb instruction set is highly optimized. Academically, the Cortex-M0 processor is classified as load-store architecture, as it has separate instructions for reading and writing to memory, and instructions for arithmetic or logical operations that use registers. • SuperVisor Call (SVC) instruction with a dedicated SVC exception and PendSV (Pendable SuperVisor service) to support various operations in an embedded OS. • Architecturally defined sleep modes and instructions to enter sleep. The sleep features allow power consumption to be reduced dramatically. Defining sleep modes as an architectural feature makes porting of software easier because sleep is entered by a specific instruction rather than implementation defined control registers. • Fault handling exception to catch various sources of errors in the system. • Support for 24 interrupts. • Little endian memory support. • Wake up Interrupt Controller (WIC) to allow the processor to be powered down during sleep, while still allowing interrupt sources to wake up the system. • Halt mode debug. Allows the processor activity to stop completely so that register values can be accessed and modified. No overhead in code size and stack memory size. • CoreSight technology. Allows memories and peripherals to be accessed from the debugger without halting the processor. • Thumb instruction set. Highly efficient, high code density and able to execute all Thumb instructions from the ARM7TDMI processor. • Supports Serial Wire Debug (SWD) connections. The serial wire debug protocol can handle the same debug features as the JTAG, but it only requires two wires and is already supported by a number of debug solutions from various tools vendors. • High performance. Up to 0.9 DMIPS/MHz (Dhrystone 2.1) with fast multiplier. • Four (4) hardware breakpoints and two (2) watch points. • Built-in Nested Vectored Interrupt Controller (NVIC). This makes interrupt configuration and coding of exception handlers easy. When an interrupt request is taken, the corresponding interrupt handler is executed automatically without the need to determine the exception vector in software. • Breakpoint instruction support for an unlimited number of software breakpoints. Features • Interrupts can have four different programmable priority levels. The NVIC automatically handles nested interrupts. • Programmer’s model similar to the ARM7TDMI processor. Most existing Thumb code for the ARM7TDMI processor can be reused. This also makes it easy for ARM7TDMI users, as there is no need to learn a new instruction set. • The design is configured to respond to exceptions (e.g. interrupts) as soon as possible (minimum 16 clock cycles). 4.2 BLUETOOTH SMART • Non maskable interrupt (NMI) input for safety critical systems. The BLE (Bluetooth low energy) core is a qualified Bluetooth baseband controller compatible with the Bluetooth low energy 4.2 specification and it is in charge of packet encoding/decoding and frame scheduling. • Easy to use and C friendly. There are only two modes (Thread mode and Handler mode). The whole application, including exception handlers, can be written in C without any assembler. • Built-in System Tick timer for OS support. A 24-bit timer with a dedicated exception type is included in Datasheet CFR0011-120-00-FM 4.2.1 BLE Core Features • All device classes support (Broadcaster, Central, Observer, Peripheral) Revision 3.4 9 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL • All packet types (Advertising / Data / Control) • Encryption (AES / CCM) • Bit stream processing (CRC, Whitening) • FDMA/TDMA/events formatting and synchronization • Frequency hopping calculation • Operating clock 16 MHz or 8 MHz • Low power modes supporting 32.0 kHz or 32.768 kHz • Supports power down of the baseband during the protocol’s idle periods • AHB Slave interface for register file access • AHB Slave interface for Exchange Memory access of CPU via BLE core • AHB Master interface for direct access of BLE core to Exchange Memory space 4.2.2 Radio Transceiver The Radio Transceiver implements the RF part of the Bluetooth low energy protocol. Together with the Bluetooth 4.2 PHY layer, this provides a 93 dB RF link budget for reliable wireless communication. All RF blocks are supplied by on-chip low-drop out-regulators (LDOs). The bias scheme is programmable per block and optimized for minimum power consumption. The Bluetooth LE radio comprises the Receiver, Transmitter, Synthesizer, Rx/Tx combiner block, and Biasing LDOs. Figure 5: SmartSnippets Stack Apart from the protocol stack, the Software platform supports a Hardware Abstraction Layer (HAL) which enables easy access to peripheral’s features from a programmer’s point of view, as presented in the following figure. Features • Single ended RFIO interface, 50  matched • Alignment free operation • -93 dBm receiver sensitivity • 0 dBm transmit output power • Ultra low power consumption • Fast frequency tuning minimizes overhead 4.2.3 SmartSnippets The DA14580 comes complete with Dialog’s SmartSnippets Bluetooth Software platform which includes a qualified Bluetooth Smart single-mode stack on chip. Numerous Bluetooth Smart profiles for consumer wellness, sport, fitness, security and proximity applications are supplied as standard, while additional customer profiles can be developed and added as needed. The SmartSnippets software development environment is based on Keil’s uVision mature tools and contains example application code for both embedded and hosted modes. Datasheet CFR0011-120-00-FM Revision 3.4 10 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Application Accelerometer  Driver SPI FLASH  Driver Sample  Drivers Battery Driver CORE Drivers EEPROM I2C Driver GPIO  Driver SPI Driver UART Driver ADC Driver Quadrature  Timers Figure 6: Hardware Abstraction Layer Core drivers are provided for each interface of the DA14580 enabling optimized usage of the hardware’s capabilities. These drivers provide an easy-to-use interface towards the hardware engines without having to interfere with the register programming directly. On top of the core drivers, a number of sample drivers is also provided enabling communication with basic Bluetooth Smart application components: accelerometers, FLASH/EEPROM non-volatile memories, etc. 4.3 MEMORIES The following memories are part of the DA14580’s internal blocks: ROM. This is a 84 kB ROM containing the Bluetooth low energy protocol stack as well as the boot code sequence. OTP. This is a 32 kB One-Time Programmable memory array, used to store the application code as well as Bluetooth low energy profiles. It also contains the system configuration and calibration data. System SRAM. This is a 42 kB system SRAM (SysRAM) which is primarily used for mirroring the program code from the OTP when the system wakes/powers up. It also serves as Data RAM for intermediate variables and various data that the protocol requires. Optionally, it can be used as extra memory space for the BLE TX and RX data structures. Retention RAMs. These are 4 special low leakage SRAM cells (2 kB + 2 kB + 3 kB + 1 kB) used to store various data of the Bluetooth low energy protocol as well as the system’s global variables and processor stack when the system goes into Deep Sleep mode. Storage of this data ensures secure and quick configuration of the BLE Core after the system wakes up. Every cell can be powered on or off according to the application needs for retention area when in Deep Datasheet CFR0011-120-00-FM Sleep mode. 4.4 FUNCTIONAL MODES The DA14580 is optimized for deeply embedded applications such as health monitoring, sports measuring, human interaction devices etc. Customers are able to develop and test their own applications. Upon completion of the development, the application code can be programmed into the OTP. In general, the system has three functional modes of operation: A. Development Mode: During this phase application code is developed using the ARM Cortex-M0 SW environment. The compiled code is then downloaded into the System RAM or any Retention RAMs by means of SWD (JTAG) or any serial interface (e.g. UART). Address 0x00 is remapped to the physical memory that contains the code and the CPU is configured to reset and execute code from the remapped device. This mode is enabling application development, debugging and on-the-fly testing. B. Normal Mode: After the application is ready and verified, the code can be burned into the OTP. When the system boots/wakes up, the DMA of the OTP controller will automatically copy the program code from the OTP into the system RAM. Next, a SW reset or a jump to the System RAM occurs and code execution is started. Hence, in this mode, the system is autonomous, contains the required SW in OTP and is ready for integration into the final product. C. Calibration Mode: Between Development and Normal mode, there is an intermediate stage where the chip needs to be calibrated with respect to two important features: • Programming of the Bluetooth device address • Programming of the trimming value for the external 16 MHz crystal. Revision 3.4 11 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL This mode of operation applies to the final product and is performed by the customer. During this phase, certain fields in the OTP should be programmed. 4.5 POWER MODES There are four different power modes in the DA14580: • Active mode: System is active and operates at full speed. • Sleep mode: No power gating has been programmed, the ARM CPU is idle, waiting for an interrupt. PD_SYS is on. PD_PER and PED_RAD depending on the programmed enabled value. • Extended Sleep mode: All power domains are off except for the PD_AON, the programmed PD_RRx and the PD_SR. Since the SysRAM retains its data, no OTP mirroring is required upon waking up the system. • Deep Sleep mode: All power domains are off except for the PD_AON and the programmed PD_RRx. This mode dissipates the minimum leakage power. However, since the SysRAM has not retained its data, an OTP mirror action is required upon waking up the system. • Prioritized interrupt identification • Programmable serial data baud rate as calculated by the following: baud rate = (serial clock frequency)/ (divisor). 4.6.2 SPI+ This interface supports a subset of the Serial Peripheral Interface (SPITM). The serial interface can transmit and receive 8, 16 or 32 bits in master/slave mode and transmit 9 bits in master mode. The SPI+ interface has enhanced functionality with bidirectional 2x16-bit word FIFOs. SPI is a trademark of Motorola, Inc. Features • Slave and Master mode • 8 bit, 9 bit, 16 bit or 32 bit operation • Clock speeds up to 16 MHz for the SPI controller. Programmable output frequencies of SPI source clock divided by 1, 2, 4, 8 • SPI clock line speed up to 8 MHz • SPI mode 0, 1, 2, 3 support (clock edge and phase) 4.6 INTERFACES • Programmable SPI_DO idle level 4.6.1 UARTs • Maskable Interrupt generation The UART is compliant to the industry-standard 16550 and is used for serial communication with a peripheral, modem (data carrier equipment, DCE) or data set. Data is written from a master (CPU) over the APB bus to the UART and it is converted to serial form and transmitted to the destination device. Serial data is also received by the UART and stored for the master (CPU) to read back. • Bus load reduction by unidirectional writes-only and reads-only modes. Built-in RX/TX FIFOs for continuous SPI bursts. 4.6.3 I2C Interface Features The I2C interface is a programmable control bus that provides support for the communications link between Integrated Circuits in a system. It is a simple two-wire bus with a software-defined protocol for system control, which is used in temperature sensors and voltage level translators to EEPROMs, general-purpose I/O, A/D and D/A converters. • 16 bytes Transmit and receive FIFOs Features • Hardware flow control support (CTS/RTS) • Two-wire I2C serial interface consists of a serial data line (SDA) and a serial clock (SCL) There is no DMA support on the UART block since its contains internal FIFOs. Both UARTs support hardware flow control signals (RTS, CTS, DTR, DSR). • Shadow registers to reduce software overhead and also include a software programmable reset • Two speeds are supported: • Transmitter Holding Register Empty (THRE) interrupt mode • Standard mode (0 to 100 kbit/s) • IrDA 1.0 SIR mode supporting low power mode. • Clock synchronization • Functionality based on the 16550 industry standard: • 32 deep transmit/receive FIFOs • Programmable character properties, such as number of data bits per character (5-8), optional • Master transmit, Master receive operation • parity bit (with odd or even select) and number of stop bits (1, 1.5 or 2) • 7 or 10-bit combined format transfers • Line break generation and detection • Fast mode ( 1.4 V) Figure 10: DC-DC Efficiency in Buck/Boost Mode at Various Voltage Levels The X axis represents the supply voltage. BOOST mode should be used when voltage ranges from 0.9 V to 2.0 V to sustain a decent efficiency over 70 %. From that point on, the power dissipation becomes quite large. BUCK mode can operate correctly with voltages in the range of 2.35 V to 3.3 V. There are two voltage areas in Figure 10 designated by dashed lines. The first one (0 V to 0.9 V) indicates that the DA14580 is not operational when the voltage is below 0.9 V. This is the absolute threshold for the DCDC converter Boost mode. The second area (1.8 V to 2.2 V) indicates that Deep Sleep mode is not allowed when the DC-DC converter is configured in BUCK mode and the voltage is within this range, because the OTP will not be readable any more. However, this part of the voltage range can be covered by the BOOST mode. Furthermore, when BUCK mode is mandatory, Extended Sleep mode can be activated instead of Deep Sleep mode, thus not using the OTP for the code mirroring but retain the code in SysRAM. Note: The system should never be cold booted when the supply voltage is less than 2.5 V. A manual power up with a power supply less than 2.5 V in buck mode might create instability.

The data in this register is valid only if the Data Ready (DR) bit in the Line status Register (LSR) is set. If FIFOs are disabled (FCR[0] set to zero), the data in the RBR must be read before the next data arrives, otherwise it will be overwritten, resulting in an overrun error. If FIFOs are enabled (FCR[0] set to one), this register accesses the head of the receive FIFO. If the receive FIFO is full and this register is not read before the next data character arrives, then the data already in the FIFO will be preserved but any incoming data will be lost. An overrun error will also occur. Transmit Holding Register: This register contains data to be transmitted on the serial output port (sout) in UART mode or the serial infrared output (sir_out_n) in infrared mode. Data should only be written to the THR when the THR Empty (THRE) bit (LSR[5]) is set. If FIFO's are disabled (FCR[0] set to zero) and THRE is set, writing a single character to the THR clears the THRE. Any additional writes to the THR before the THRE is set again causes the THR data to be overwritten. If FIFO's are enabled (FCR[0] set to one) and THRE is set, x number of characters of data may be written to the THR before the FIFO is full. The number x (default=16) is determined by the value of FIFO Depth that you set during configuration. Any attempt to write data when the FIFO is full results in the write data being lost. Divisor Latch (Low): This register makes up the lower 8bits of a 16-bit, read/write, Divisor Latch register that contains the baud rate divisor for the UART. This register may only be accessed when the DLAB bit (LCR[7]) is set. The output baud rate is equal to the serial clock (sclk) frequency divided by sixteen times the value of the baud rate divisor, as follows: baud rate = (serial clock freq) / (16 * divisor) Note that with the Divisor Latch Registers (DLL and DLH) set to zero, the baud clock is disabled and no serial communications will occur. Also, once the DLL is set, at least 8 clock cycles of the slowest DW_apb_uart clock should be allowed to pass before transmitting or receiving data. 0x0 Table 48: UART_IER_DLH_REG (0x50001004) Bit Mode Symbol Description Reset 15:8 - - Reserved 0x0 7 R/W PTIME_DLH7 Interrupt Enable Register: PTIME, Programmable THRE Interrupt Mode Enable.

This is used to put the UART into a diagnostic mode for test purposes. If operating in UART mode (SIR_MODE not active, MCR[6] set to zero), data on the sout line is held high, while serial data output is looped back to the sin line, internally. In this mode all the interrupts are fully functional. Also, in loopback mode, the modem control inputs (dsr_n, cts_n, ri_n, dcd_n) are disconnected and the modem control outputs (dtr_n, rts_n, out1_n, out2_n) are looped back to the inputs, internally. If operating in infrared mode (SIR_MODE active, MCR[6] set to one), data on the sir_out_n line is held low, while serial data output is inverted and looped back to the sir_in line. 0x0 3 R/W UART_OUT2 OUT2. This is used to directly control the user-designated Output2 (out2_n) output. The value written to this location is inverted and driven out on out2_n, that is: 0 = out2_n de-asserted (logic 1) 1 = out2_n asserted (logic 0) Note that in Loopback mode (MCR[4] set to one), the out2_n output is held inactive high while the value of this location is internally looped back to an input. 0x0 2 R/W UART_OUT1 OUT1. This is used to directly control the user-designated Output1 (out1_n) output. The value written to this location is inverted and driven out on out1_n, that is: 0 = out1_n de-asserted (logic 1) 1 = out1_n asserted (logic 0) Note that in Loopback mode (MCR[4] set to one), the out1_n output is held inactive high while the value of this location is internally looped back to an input. 0x0 1 R/W UART_RTS Request to Send. This is used to directly control the Request to Send (rts_n) output. The Request To Send (rts_n) output is used to inform the modem or data set that the UART is ready to exchange data. When Auto Flow Control is disabled (MCR[5] set to zero), the rts_n signal is set low by programming MCR[1] (RTS) to a high. When Auto Flow Control is enabled (MCR[5] set to one) and FIFOs are enabled (FCR[0] set to one), the rts_n output is controlled in the same way, but is also gated with the receiver FIFO threshold trigger (rts_n is inactive high when above the threshold). The rts_n signal is de-asserted when MCR[1] is set low. Note that in Loopback mode (MCR[4] set to one), the rts_n output is held inactive (high) while the value of this location is internally looped back to an input. 0x0 0 - - Reserved 0x0 Table 52: UART_LSR_REG (0x50001014) Bit Mode Symbol Description Reset 15:8 - - Reserved 0x0 Datasheet CFR0011-120-01 Revision 3.4 42 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Table 52: UART_LSR_REG (0x50001014) Bit Mode Symbol Description Reset 7 R UART_RFE Receiver FIFO Error bit. This bit is only relevant when FIFOs are enabled (FCR[0] set to one). This is used to indicate if there is at least one parity error, framing error, or break indication in the FIFO. 0 = no error in RX FIFO 1 = error in RX FIFO This bit is cleared when the LSR is read and the character with the error is at the top of the receiver FIFO and there are no subsequent errors in the FIFO. 0x0 6 R UART_TEMT Transmitter Empty bit. If FIFOs enabled (FCR[0] set to one), this bit is set whenever the Transmitter Shift Register and the FIFO are both empty. If FIFOs are disabled, this bit is set whenever the Transmitter Holding Register and the Transmitter Shift Register are both empty. 0x1 5 R UART_THRE Transmit Holding Register Empty bit. If THRE mode is disabled (IER[7] set to zero) and regardless of FIFO's being implemented/enabled or not, this bit indicates that the THR or TX FIFO is empty. This bit is set whenever data is transferred from the THR or TX FIFO to the transmitter shift register and no new data has been written to the THR or TX FIFO. This also causes a THRE Interrupt to occur, if the THRE Interrupt is enabled. If both modes are active (IER[7] set to one and FCR[0] set to one respectively), the functionality is switched to indicate the transmitter FIFO is full, and no longer controls THRE interrupts, which are then controlled by the FCR[5:4] threshold setting. 0x1 4 R UART_B1 Break Interrupt bit. This is used to indicate the detection of a break sequence on the serial input data. If in UART mode (SIR_MODE == Disabled), it is set whenever the serial input, sin, is held in a logic '0' state for longer than the sum of start time + data bits + parity + stop bits. If in infrared mode (SIR_MODE == Enabled), it is set whenever the serial input, sir_in, is continuously pulsed to logic '0' for longer than the sum of start time + data bits + parity + stop bits. A break condition on serial input causes one and only one character, consisting of all zeros, to be received by the UART. In the FIFO mode, the character associated with the break condition is carried through the FIFO and is revealed when the character is at the top of the FIFO. Reading the LSR clears the BI bit. In the non-FIFO mode, the BI indication occurs immediately and persists until the LSR is read. 0x0 Datasheet CFR0011-120-01 Revision 3.4 43 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Table 52: UART_LSR_REG (0x50001014) Bit Mode Symbol Description Reset 3 R UART_FE Framing Error bit. This is used to indicate the occurrence of a framing error in the receiver. A framing error occurs when the receiver does not detect a valid STOP bit in the received data. In the FIFO mode, since the framing error is associated with a character received, it is revealed when the character with the framing error is at the top of the FIFO. When a framing error occurs, the UART tries to resynchronize. It does this by assuming that the error was due to the start bit of the next character and then continues receiving the other bit i.e. data, and/or parity and stop. It should be noted that the Framing Error (FE) bit (LSR[3]) is set if a break interrupt has occurred, as indicated by Break Interrupt (BI) bit (LSR[4]). 0 = no framing error 1 = framing error Reading the LSR clears the FE bit. 0x0 2 R UART_PE Parity Error bit. This is used to indicate the occurrence of a parity error in the receiver if the Parity Enable (PEN) bit (LCR[3]) is set. In the FIFO mode, since the parity error is associated with a character received, it is revealed when the character with the parity error arrives at the top of the FIFO. It should be noted that the Parity Error (PE) bit (LSR[2]) is set if a break interrupt has occurred, as indicated by Break Interrupt (BI) bit (LSR[4]). 0 = no parity error 1 = parity error Reading the LSR clears the PE bit. 0x0 1 R UART_OE Overrun error bit. This is used to indicate the occurrence of an overrun error. This occurs if a new data character was received before the previous data was read. In the non-FIFO mode, the OE bit is set when a new character arrives in the receiver before the previous character was read from the RBR. When this happens, the data in the RBR is overwritten. In the FIFO mode, an overrun error occurs when the FIFO is full and a new character arrives at the receiver. The data in the FIFO is retained and the data in the receive shift register is lost. 0 = no overrun error 1 = overrun error Reading the LSR clears the OE bit. 0x0 0 R UART_DR Data Ready bit. This is used to indicate that the receiver contains at least one character in the RBR or the receiver FIFO. 0 = no data ready 1 = data ready This bit is cleared when the RBR is read in non-FIFO mode, or when the receiver FIFO is empty, in FIFO mode. 0x0 Table 53: UART_MSR_REG (0x50001018) Bit Mode Symbol Description Reset 15:8 - - Reserved 0x0 Datasheet CFR0011-120-01 Revision 3.4 44 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Table 53: UART_MSR_REG (0x50001018) Bit Mode Symbol Description Reset 7 R UART_DCD Data Carrier Detect.

This is used to indicate that the modem control line dcd_n has changed since the last time the MSR was read. 0 = no change on dcd_n since last read of MSR 1 = change on dcd_n since last read of MSR Reading the MSR clears the DDCD bit. In Loopback Mode (MCR[4] = 1), DDCD reflects changes on MCR[3] (Out2). Note, if the DDCD bit is not set and the dcd_n signal is asserted (low) and a reset occurs (software or otherwise), then the DDCD bit is set when the reset is removed if the dcd_n signal remains asserted. 0x0 2 R UART_TERI Trailing Edge of Ring Indicator. This is used to indicate that a change on the input ri_n (from an active-low to an inactive-high state) has occurred since the last time the MSR was read. 0 = no change on ri_n since last read of MSR 1 = change on ri_n since last read of MSR Reading the MSR clears the TERI bit. In Loopback Mode (MCR[4] = 1), TERI reflects when MCR[2] (Out1) has changed state from a high to a low. 0x0 1 - - Reserved 0x0 Datasheet CFR0011-120-01 Revision 3.4 45 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Table 53: UART_MSR_REG (0x50001018) Bit Mode Symbol Description Reset 0 R UART_DCTS Delta Clear to Send.

This is required for SIR Low Power (minimum pulse width) detection at the receiver. This register may be accessed only when the DLAB bit (LCR[7]) is set. The output low-power baud rate is equal to the serial clock (sclk) frequency divided by sixteen times the value of the baud rate divisor, as follows: Low power baud rate = (serial clock frequency)/(16* divisor) Therefore, a divisor must be selected to give a baud rate of 115.2K. NOTE: When the Low Power Divisor Latch registers (LPDLL and LPDLH) are set to 0, the low-power baud clock is disabled and no low-power pulse detection (or any pulse detection) occurs at the receiver.

When in Loopback Mode, the break condition is internally looped back to the receiver and the sir_out_n line is forced low. 0x0 5 - - Reserved 0x0 4 R/W UART_EPS Even Parity Select. This is used to select between even and odd parity, when parity is enabled (PEN set to one). If set to one, an even number of logic 1s is transmitted or checked. If set to zero, an odd number of logic 1s is transmitted or checked. 0x0 3 R/W UART_PEN Parity Enable. This bit is used to enable and disable parity generation and detection in transmitted and received serial character respectively. 0 = parity disabled 1 = parity enabled 0x0 2 R/W UART_STOP Number of stop bits. This is used to select the number of stop bits per character that the peripheral transmits and receives. If set to zero, one stop bit is transmitted in the serial data. If set to one and the data bits are set to 5 (LCR[1:0] set to zero) one and a half stop bits is transmitted. Otherwise, two stop bits are transmitted. Note that regardless of the number of stop bits selected, the receiver checks only the first stop bit. 0 = 1 stop bit 1 = 1.5 stop bits when DLS (LCR[1:0]) is zero, else 2 stop bit 0x0 1:0 R/W UART_DLS Data Length Select. This is used to select the number of data bits per character that the peripheral transmits and receives.

This is used to put the UART into a diagnostic mode for test purposes. If operating in UART mode (SIR_MODE not active, MCR[6] set to zero), data on the sout line is held high, while serial data output is looped back to the sin line, internally. In this mode all the interrupts are fully functional. Also, in loopback mode, the modem control inputs (dsr_n, cts_n, ri_n, dcd_n) are disconnected and the modem control outputs (dtr_n, rts_n, out1_n, out2_n) are looped back to the inputs, internally. If operating in infrared mode (SIR_MODE active, MCR[6] set to one), data on the sir_out_n line is held low, while serial data output is inverted and looped back to the sir_in line. 0x0 3 R/W UART_OUT2 OUT2. This is used to directly control the user-designated Output2 (out2_n) output. The value written to this location is inverted and driven out on out2_n, that is: 0 = out2_n de-asserted (logic 1) 1 = out2_n asserted (logic 0) Note that in Loopback mode (MCR[4] set to one), the out2_n output is held inactive high while the value of this location is internally looped back to an input. 0x0 2 R/W UART_OUT1 OUT1. This is used to directly control the user-designated Output1 (out1_n) output. The value written to this location is inverted and driven out on out1_n, that is: 0 = out1_n de-asserted (logic 1) 1 = out1_n asserted (logic 0) Note that in Loopback mode (MCR[4] set to one), the out1_n output is held inactive high while the value of this location is internally looped back to an input. 0x0 1 R/W UART_RTS Request to Send. This is used to directly control the Request to Send (rts_n) output. The Request To Send (rts_n) output is used to inform the modem or data set that the UART is ready to exchange data. When Auto Flow Control is disabled (MCR[5] set to zero), the rts_n signal is set low by programming MCR[1] (RTS) to a high. When Auto Flow Control is enabled (MCR[5] set to one) and FIFOs are enabled (FCR[0] set to one), the rts_n output is controlled in the same way, but is also gated with the receiver FIFO threshold trigger (rts_n is inactive high when above the threshold). The rts_n signal is de-asserted when MCR[1] is set low. Note that in Loopback mode (MCR[4] set to one), the rts_n output is held inactive (high) while the value of this location is internally looped back to an input. 0x0 0 - - Reserved 0x0 Table 92: UART2_LSR_REG (0x50001114) Bit Mode Symbol Description Reset 15:8 - - Reserved 0x0 Datasheet CFR0011-120-01 Revision 3.4 71 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Table 92: UART2_LSR_REG (0x50001114) Bit Mode Symbol Description Reset 7 R UART_RFE Receiver FIFO Error bit. This bit is only relevant when FIFOs are enabled (FCR[0] set to one). This is used to indicate if there is at least one parity error, framing error, or break indication in the FIFO. 0 = no error in RX FIFO 1 = error in RX FIFO This bit is cleared when the LSR is read and the character with the error is at the top of the receiver FIFO and there are no subsequent errors in the FIFO. 0x0 6 R UART_TEMT Transmitter Empty bit. If FIFOs enabled (FCR[0] set to one), this bit is set whenever the Transmitter Shift Register and the FIFO are both empty. If FIFOs are disabled, this bit is set whenever the Transmitter Holding Register and the Transmitter Shift Register are both empty. 0x1 5 R UART_THRE Transmit Holding Register Empty bit. If THRE mode is disabled (IER[7] set to zero) and regardless of FIFO's being implemented/enabled or not, this bit indicates that the THR or TX FIFO is empty. This bit is set whenever data is transferred from the THR or TX FIFO to the transmitter shift register and no new data has been written to the THR or TX FIFO. This also causes a THRE Interrupt to occur, if the THRE Interrupt is enabled. If both modes are active (IER[7] set to one and FCR[0] set to one respectively), the functionality is switched to indicate the transmitter FIFO is full, and no longer controls THRE interrupts, which are then controlled by the FCR[5:4] threshold setting. 0x1 4 R UART_B1 Break Interrupt bit. This is used to indicate the detection of a break sequence on the serial input data. If in UART mode (SIR_MODE == Disabled), it is set whenever the serial input, sin, is held in a logic '0' state for longer than the sum of start time + data bits + parity + stop bits. If in infrared mode (SIR_MODE == Enabled), it is set whenever the serial input, sir_in, is continuously pulsed to logic '0' for longer than the sum of start time + data bits + parity + stop bits. A break condition on serial input causes one and only one character, consisting of all zeros, to be received by the UART. In the FIFO mode, the character associated with the break condition is carried through the FIFO and is revealed when the character is at the top of the FIFO. Reading the LSR clears the BI bit. In the non-FIFO mode, the BI indication occurs immediately and persists until the LSR is read. 0x0 Datasheet CFR0011-120-01 Revision 3.4 72 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Table 92: UART2_LSR_REG (0x50001114) Bit Mode Symbol Description Reset 3 R UART_FE Framing Error bit. This is used to indicate the occurrence of a framing error in the receiver. A framing error occurs when the receiver does not detect a valid STOP bit in the received data. In the FIFO mode, since the framing error is associated with a character received, it is revealed when the character with the framing error is at the top of the FIFO. When a framing error occurs, the UART tries to resynchronize. It does this by assuming that the error was due to the start bit of the next character and then continues receiving the other bit i.e. data, and/or parity and stop. It should be noted that the Framing Error (FE) bit (LSR[3]) is set if a break interrupt has occurred, as indicated by Break Interrupt (BI) bit (LSR[4]). 0 = no framing error 1 = framing error Reading the LSR clears the FE bit. 0x0 2 R UART_PE Parity Error bit. This is used to indicate the occurrence of a parity error in the receiver if the Parity Enable (PEN) bit (LCR[3]) is set. In the FIFO mode, since the parity error is associated with a character received, it is revealed when the character with the parity error arrives at the top of the FIFO. It should be noted that the Parity Error (PE) bit (LSR[2]) is set if a break interrupt has occurred, as indicated by Break Interrupt (BI) bit (LSR[4]). 0 = no parity error 1 = parity error Reading the LSR clears the PE bit. 0x0 1 R UART_OE Overrun error bit. This is used to indicate the occurrence of an overrun error. This occurs if a new data character was received before the previous data was read. In the non-FIFO mode, the OE bit is set when a new character arrives in the receiver before the previous character was read from the RBR. When this happens, the data in the RBR is overwritten. In the FIFO mode, an overrun error occurs when the FIFO is full and a new character arrives at the receiver. The data in the FIFO is retained and the data in the receive shift register is lost. 0 = no overrun error 1 = overrun error Reading the LSR clears the OE bit. 0x0 0 R UART_DR Data Ready bit. This is used to indicate that the receiver contains at least one character in the RBR or the receiver FIFO. 0 = no data ready 1 = data ready This bit is cleared when the RBR is read in non-FIFO mode, or when the receiver FIFO is empty, in FIFO mode. 0x0 Table 93: UART2_MSR_REG (0x50001118) Bit Mode Symbol Description Reset 15:8 - - Reserved 0x0 Datasheet CFR0011-120-01 Revision 3.4 73 of 155 09-Nov-2016 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC FINAL Table 93: UART2_MSR_REG (0x50001118) Bit Mode Symbol Description Reset 7 R UART_DCD Data Carrier Detect.

This bit does not control the direction when the I2C Ctrl acts as a slave. It controls only the direction when it acts as a master. 1 = Read 0 = Write When a command is entered in the TX FIFO, this bit distinguishes the write and read commands. In slave-receiver mode, this bit is a "don't care" because writes to this register are not required. In slave-transmitter mode, a "0" indicates that CPU data is to be transmitted and as DAT or IC_DATA_CMD[7:0]. When programming this bit, you should remember the following: attempting to perform a read operation after a General Call command has been sent results in a TX_ABRT interrupt (bit 6 of the I2C_RAW_INTR_STAT_REG), unless bit 11 (SPECIAL) in the I2C_TAR register has been cleared. If a "1" is written to this bit after receiving a RD_REQ interrupt, then a TX_ABRT interrupt occurs. NOTE: It is possible that while attempting a master I2C read transfer on the controller, a RD_REQ interrupt may have occurred simultaneously due to a remote I2C master addressing the controller. In this type of scenario, it ignores the I2C_DATA_CMD write, generates a TX_ABRT interrupt, and waits to service the RD_REQ interrupt 0x0 7:0 R/W DAT This register contains the data to be transmitted or received on the I2C bus.

WLCSP packages are qualified for MSL 1. QFN packages are qualified for MSL 3. MSL Level Floor Life Time MSL 4 72 hours MSL 3 168 hours MSL 2A 4 weeks MSL 2 1 year MSL 1 Unlimited at 30 °C / 85 % RH 7.2 WLCSP HANDLING Manual handling of WLCSP packages should be reduced to the absolute minimum. In cases where it is still necessary, a vacuum pick-up tool should be used. In extreme cases plastic tweezers could be used, but metal tweezers are not acceptable, since contact may easily damage the silicon chip. Removal will cause damage to the solder balls and therefore a removed sample cannot be reused. WLCSP is sensitive to visible and infrared light. Precautions should be taken to properly shield the chip in the final product. 7.3 SOLDERING INFORMATION Refer to the JEDEC standard J-STD-020 for relevant soldering information.
