Series combines a powerful 8051-based microcontroller with a flexible memory structure, programmable logic, and a rich peripheral mix to form an ideal embedded controller. At its core is a fast 4-cycle 8032 MCU with a 4-byte instruction prefetch queue (PFQ) and a 4-entry fully associative branching cache (BC). The MCU is connected to a 16-bit internal instruction path to maximize performance, enabling loops of code in smaller localities to execute extremely fast. The 16-bit wide instruction path in the Turbo Plus Series allows double-byte instructions to be fetched from memory in a single memory cycle. This keeps the average performance near its peak performance (peak performance for 5V, 40MHz Turbo Plus uPSD34xx is 10 MIPS for single-byte instructions, and average performance will be approximately 9 MIPS for mix of single- and multi-byte instructions). USB 2.0 (full speed, 12Mbps) is included, providing 10 endpoints, each with its own 64-byte FIFO to maintain high data throughput. Endpoint 0 (Control Endpoint) uses two of the 10 endpoints for In and Out directions, the remaining eight endpoints may be allocated in any mix to either type of transfers: Bulk or Interrupt. Code development is easily managed without a hardware In-Circuit Emulator by using the serial JTAG debug interface. JTAG is also used for In-System Programming (ISP) in as little as 10 seconds, perfect for manufacturing and lab development. The 8032 core is coupled to Programmable System Device (PSD) architecture to optimize the 8032 memory structure, offering two independent banks of Flash memory that can be placed at virtually any address within 8032 program or data address space, and easily paged beyond 64K bytes using onchip programmable decode logic. Dual Flash memory banks provide a robust solution for remote product updates in the field through In-Application Programming (IAP). Dual Flash banks also support EEPROM emulation, eliminating the need for external EEPROM chips. General purpose programmable logic (PLD) is included to build an endless variety of gluelogic, saving external logic devices. The PLD is configured using the software development tool, PSDsoft Express, available from the web at www.st.com/psm, at no charge. The uPSD34xx also includes supervisor functions such as a programmable watchdog timer and low-voltage reset. Note: For a list of known limitations of the uPSD34xx devices, please refer to Section 34: Important notes. 9/293 Summary description Figure 2.

There are two die, one is designated “MCU Module” in this document, and the other is designated “PSD Module” (see Figure 5 on page 18). In all cases, the MCU Module die operates at 3.3V with 5V tolerant I/O. The PSD Module is either a 3.3V die or a 5V die, depending on the uPSD34xx device as described below. The MCU Module consists of a fast 8032 core, that operates with 4 clocks per instruction cycle, and has many peripheral and system supervisor functions. The PSD Module provides the 8032 with multiple memories (two Flash and one SRAM) for program and data, programmable logic for address decoding and for general-purpose logic, and additional I/O. The MCU Module communicates with the PSD Module through internal address and data busses (AD0 – AD15) and control signals (RD, WR, PSEN, ALE, RESET). There are slightly different I/O characteristics for each module. I/Os for the MCU module are designated as Ports 1, 3, and 4. I/Os for the PSD Module are designated as Ports A, B, C, and D. For all 5V uPSD34xx devices, a 3.3V MCU Module is stacked with a 5V PSD Module. In this case, a 5V uPSD34xx device must be supplied with 3.3VCC for the MCU Module and 5.0VDD for the PSD Module. Ports 3 and 4 of the MCU Module are 3.3V ports with tolerance to 5V devices (they can be directly driven by external 5V devices and they can directly drive external 5V devices while producing a VOH of 2.4V min and VCC max). Ports A, B, C, and D of the PSD Module are true 5V ports. For all 3.3V uPSD34xxV devices, a 3.3V MCU Module is stacked with a 3.3V PSD Module. In this case, a 3.3V uPSD34xx device needs to be supplied with a single 3.3V voltage source at both VCC and VDD. I/O pins on Ports 3 and 4 are 5V tolerant and can be connected to external 5V peripherals devices if desired. Ports A, B, C, and D of the PSD Module are 3.3V ports, which are not tolerant to external 5V devices. Refer to Table 3 for port type and voltage source requirements. 80-pin uPSD34xx devices provide access to 8032 address, data, and control signals on external pins to connect external peripheral and memory devices. 52-pin uPSD34xx devices do not provide access to the 8032 system bus. All non-volatile memory and configuration portions of the uPSD34xx device are programmed through the JTAG interface and no special programming voltage is needed. This same JTAG port is also used for debugging of the 8032 core at runtime providing breakpoint, single-step, display, and trace features. A non-volatile security bit may be programmed to block all access via JTAG interface for security. The security bit is defeated only by erasing the entire device, leaving the device blank and ready to use again. Table 3.

These standard 8032 memories reside in 384 bytes of SRAM located at a fixed address space starting at address 0x0000. External memory on the PSD Module consists of four types: main Flash (64K, 128K, or 256K bytes), a smaller secondary Flash (32K), SRAM (4K, 8K or 32Kbytes), and a block of PSD Module control registers called csiop (256 bytes). These external memories reside at programmable address ranges, specified using the software tool PSDsoft Express. See the PSD Module section of this document for more details on these memories. External memory is accessed by the 8032 in two separate 64K byte address spaces. One address space is for program memory and the other address space is for data memory. Program memory is accessed using the 8032 signal, PSEN. Data memory is accessed using the 8032 signals, RD and WR. If the 8032 needs to access more than 64K bytes of external program or data memory, it must use paging (or banking) techniques provided by the Page Register in the PSD Module. Note: When referencing program and data memory spaces, it has nothing to do with 8032 internal SRAM areas of DATA, IDATA, and SFR on the MCU Module. Program and data memory spaces only relate to the external memories on the PSD Module. External memory on the PSD Module can overlap the internal SRAM memory on the MCU Module in the same physical address range (starting at 0x0000) without interference because the 8032 core does not assert the RD or WR signals when accessing internal SRAM.

Four register banks, each with 8 registers (R0 – R7), occupy addresses 0x0000 to 0x001F. Only one of these four banks may be enabled at a time. The next 16 locations at 0x0020 to 0x002F contain 128 directly addressable bit locations that can be used as software flags. SRAM locations 0x0030 and above may be used for variables and stack. 4.1.2 IDATA memory The next 128 bytes of internal SRAM are named IDATA and range from address 0x0080 to 0x00FF. IDATA can be accessed only through 8032 indirect addressing and is typically used to hold the MCU stack as well as data variables. The stack can reside in both DATA and IDATA memories and reach a size limited only by the available space in the combined 256 bytes of these two memories (since stack accesses are always done using indirect addressing, the boundary between DATA and IDATA does not exist with regard to the stack). 4.1.3 SFR memory Special Function Registers (Table 5 on page 32) occupy a separate physical memory, but they logically overlap the same 128 bytes as IDATA, ranging from address 0x0080 to 0x00FF. SFRs are accessed only using direct addressing. There 86 active registers used for many functions: changing the operating mode of the 8032 MCU core, controlling 8032 peripherals, controlling I/O, and managing interrupt functions. The remaining unused SFRs are reserved and should not be accessed. 16 of the SFRs are both byte- and bit-addressable. Bit-addressable SFRs are those whose address ends in “0” or “8” hex. 4.2 External memory (PSD module: program memory, data memory) The PSD Module has four memories: main Flash, secondary Flash, SRAM, and csiop. See the PSD MODULE section for more detailed information on these memories. Memory mapping in the PSD Module is implemented with the Decode PLD (DPLD) and optionally the Page Register. The user specifies decode equations for individual segments of each of the memories using the software tool PSDsoft Express. This is a very easy pointand-click process allowing total flexibility in mapping memories. Additionally, each of the memories may be placed in various combinations of 8032 program address space or 8032 data address space by using the software tool PSDsoft Express. 20/293 uPSD34xx Memory organization 4.2.1 Program memory External program memory is addressed by the 8032 using its 16-bit Program Counter (PC) and is accessed with the 8032 signal, PSEN. Program memory can be present at any address in program space between 0x0000 and 0xFFFF. After a power-up or reset, the 8032 begins program execution from location 0x0000 where the reset vector is stored, causing a jump to an initialization routine in firmware. At address 0x0003, just following the reset vector are the interrupt service locations. Each interrupt is assigned a fixed interrupt service location in program memory. An interrupt causes the 8032 to jump to that service location, where it commences execution of the service routine. External Interrupt 0 (EXINT0), for example, is assigned to service location 0x0003. If EXINT0 is going to be used, its service routine must begin at location 0x0003. Interrupt service locations are spaced at 8-byte intervals: 0x0003 for EXINT0, 0x000B for Timer 0, 0x0013 for EXINT1, and so forth. If an interrupt service routine is short enough, it can reside entirely within the 8-byte interval. Longer service routines can use a jump instruction to somewhere else in program memory. 4.2.2 Data memory External data is referred to as XDATA and is addressed by the 8032 using Indirect Addressing via its 16-bit Data Pointer Register (DPTR) and is accessed by the 8032 signals, RD and WR. XDATA can be present at any address in data space between 0x0000 and 0xFFFF. Note: The uPSD34xx has dual data pointers (source and destination) making XDATA transfers much more efficient. 4.2.3 Memory placement PSD Module architecture allows the placement of its external memories into different combinations of program memory and data memory spaces. This means the main Flash, the secondary Flash, and the SRAM can be viewed by the 8032 MCU in various combinations of program memory or data memory as defined by PSDsoft Express. As an example of this flexibility, for applications that require a great deal of Flash memory in data space (large lookup tables or extended data recording), the larger main Flash memory can be placed in data space and the smaller secondary Flash memory can be placed in program space. The opposite can be realized for a different application if more Flash memory is needed for code and less Flash memory for data. By default, the SRAM and csiop memories on the PSD Module must always reside in data memory space and they are treated by the 8032 as XDATA. The main Flash and secondary Flash memories may reside in program space, data space, or both. These memory placement choices specified by PSDsoft Express are programmed into non-volatile sections of the uPSD34xx, and are active at power-up and after reset. It is possible to override these initial settings during runtime for In-Application Programming (IAP). Standard 8032 MCU architecture cannot write to its own program memory space to prevent accidental corruption of firmware. However, this becomes an obstacle in typical 8032 systems when a remote update to firmware in Flash memory is required using IAP. The PSD module provides a solution for remote updates by allowing 8032 firmware to temporarily “reclassify” Flash memory to reside in data space during a remote update, then returning 21/293 Memory organization uPSD34xx Flash memory back to program space when finished. See the VM Register (Table 104 on page 197) in the PSD Module section of this document for more details. 22/293 uPSD34xx 8032 MCU core performance enhancements 5 8032 MCU core performance enhancements Before describing performance features of the uPSD34xx, let us first look at standard 8032 architecture. The clock source for the 8032 MCU creates a basic unit of timing called a machine-cycle, which is a period of 12 clocks for standard 8032 MCUs. The instruction set for traditional 8032 MCUs consists of 1, 2, and 3 byte instructions that execute in different combinations of 1, 2, or 4 machine-cycles. For example, there are one-byte instructions that execute in one machine-cycle (12 clocks), one-byte instructions that execute in four machine-cycles (48 clocks), two-byte, two-cycle instructions (24 clocks), and so on. In addition, standard 8032 architecture will fetch two bytes from program memory on almost every machine-cycle, regardless if it needs them or not (dummy fetch). This means for onebyte, one-cycle instructions, the second byte is ignored. These one-byte, one-cycle instructions account for half of the 8032's instructions (126 out of 255 opcodes). There are inefficiencies due to wasted bus cycles and idle bus times that can be eliminated. The uPSD34xx 8032 MCU core offers increased performance in a number of ways, while keeping the exact same instruction set as the standard 8032 (all opcodes, the number of bytes per instruction, and the native number a machine-cycles per instruction are identical to the original 8032). The first way performance is boosted is by reducing the machine-cycle period to just 4 MCU clocks as compared to 12 MCU clocks in a standard 8032. This shortened machine-cycle improves the instruction rate for one- or two-byte, one-cycle instructions by a factor of three (Figure 7 on page 23) compared to standard 8051 architectures, and significantly improves performance of multiple-cycle instruction types. The example in Figure 7 on page 23 shows a continuous execution stream of one- or twobyte, one-cycle instructions. The 5V uPSD34xx will yield 10 MIPS peak performance in this case while operating at 40MHz clock rate. In a typical application however, the effective performance will be lower since programs do not use only one-cycle instructions, but special techniques are implemented in the uPSD34xx to keep the effective MIPS rate as close as possible to the peak MIPS rate at all times. This is accomplished with an instruction PreFetch Queue (PFQ), a Branch Cache (BC), and a 16-bit program memory bus as shown in Figure 8 on page 24. Figure 7. Comparison of uPSD34xx with Standard 8032 Performance 1- or 2-byte, 1-cycle Instructions Instruction A Turbo uPSD34xx Execute Instruction and Pre-Fetch Next Instruction Instruction B Execute Instruction and Pre-Fetch Next Instruction Instruction C Execute Instruction and Pre-Fetch Next Instruction 4 clocks (one machine cycle) one machine cycle one machine cycle MCU Clock 12 clocks (one machine cycle) Instruction A Standard 8032 Fetch Byte for Instruction A Execute Instruction A and Fetch a Second Dummy Byte Dummy Byte is Ignored (wasted bus access) Turbo uPSD34xx executes instructions A, B, and C in the same amount of time that a standard 8032 executes only Instruction A.

The PFQ does this by running asynchronously in relation to the MCU, looking ahead to pre-fetch two bytes (word) of code from program memory during any idle bus periods. Only necessary word will be fetched (no dummy fetches like standard 8032). The PFQ will queue up to four code bytes in advance of execution, which significantly optimizes sequential program performance. However, when program execution becomes non-sequential (program branch), a typical pre-fetch queue will empty itself and reload new code, causing the MCU to stall. The Turbo uPSD34xx diminishes this problem by using a Branch Cache with the PFQ. The BC is a four-way, fully associative cache, meaning that when a program branch occurs, its branch destination address is compared simultaneously with four recent previous branch destinations stored in the BC. Each of the four cache entries contain up to four bytes of code related to a branch. If there is a hit (a match), then all four code bytes of the matching program branch are transferred immediately and simultaneously from the BC to the PFQ, and execution on that branch continues with minimal delay. This greatly reduces the chance that the MCU will stall from an empty PFQ, and improves performance in embedded control systems where it is quite common to branch and loop in relatively small code localities. By default, the PFQ and BC are enabled after power-up or reset. The 8032 can disable the PFQ and BC at runtime if desired by writing to a specific SFR (BUSCON). The memory in the PSD module operates with variable wait states depending on the value specified in the SFR named BUSCON. For example, a 5V uPSD34xx device operating at a 40MHz crystal frequency requires four memory wait states (equal to four MCU clocks). In this example, once the PFQ has one word of code, the wait states become transparent and a full 10 MIPS is achieved when the program stream consists of sequential one- or two-byte, one machine-cycle instructions as shown in Figure 7 on page 23 (transparent because a machine-cycle is four MCU clocks which equals the memory pre-fetch wait time that is also 24/293 uPSD34xx 8032 MCU core performance enhancements four MCU clocks). But it is also important to understand PFQ operation on multi-cycle instructions. 5.2 PFQ example, multi-cycle instructions Let us look at a string of two-byte, two-cycle instructions in Figure 9 on page 25. There are three instructions executed sequentially in this example, instructions A, B, and C. Each of the time divisions in the figure is one machine-cycle of four clocks, and there are six phases to reference in this discussion. Each instruction is pre-fetched into the PFQ in advance of execution by the MCU. Prior to Phase 1, the PFQ has pre-fetched the two instruction bytes (A1 and A2) of Instruction A. During Phase one, both bytes are loaded into the MCU execution unit. Also in Phase 1, the PFQ is pre-fetching Instruction B (bytes B1 and B2) from program memory. In Phase 2, the MCU is processing Instruction A internally while the PFQ is pre-fetching Instruction C. In Phase 3, both bytes of instruction B are loaded into the MCU execution unit and the PFQ begins to pre-fetch bytes for the next instruction. In Phase 4 Instruction B is processed. The uPSD34xx MCU instructions are an exact 1/3 scale of all standard 8032 instructions with regard to number of cycles per instruction. Figure 10 on page 26 shows the equivalent instruction sequence from the example above on a standard 8032 for comparison. 5.3 Aggregate performance The stream of two-byte, two-cycle instructions in Figure 9 on page 25, running on a 40MHz, 5V, uPSD34xx will yield 5 MIPs. And we saw the stream of one- or two-byte, one-cycle instructions in Figure 7 on page 23, on the same MCU yield 10 MIPs. Effective performance will depend on a number of things: the MCU clock frequency; the mixture of instructions types (bytes and cycles) in the application; the amount of time an empty PFQ stalls the MCU (mix of instruction types and misses on Branch Cache); and the operating voltage. A 5V uPSD34xx device operates with four memory wait states, but a 3.3V device operates with five memory wait states yielding 8 MIPS peak compared to 10 MIPs peak for 5V device. The same number of wait states will apply to both program fetches and to data READ/WRITEs unless otherwise specified in the SFR named BUSCON. In general, a 3X aggregate performance increase is expected over any standard 8032 application running at the same clock frequency. Figure 9.

Figure 11. 8032 MCU registers A B SP PCH PCL PSW R0-R7 DPTR(DPH) AI06636 Accumulator B Register Stack Pointer Program Counter Program Status Word General Purpose Register (Bank0-3) Data Pointer Register DPTR(DPL) 7.1 Stack pointer (SP) The SP is an 8-bit register which holds the current location of the top of the stack. It is incremented before a value is pushed onto the stack, and decremented after a value is popped off the stack. The SP is initialized to 07h after reset. This causes the stack to begin at location 08h (top of stack). To avoid overlapping conflicts, the user must initialize the top of the stack to 20h if all four banks of registers R0 - R7 are used, as well as the top of stack to 30h if all of the 8032 bit memory locations are used. 7.2 Data pointer (DPTR) DPTR is a 16-bit register consisting of two 8-bit registers, DPL and DPH. The DPTR Register is used as a base register to create an address for indirect jumps, table look-up operations, and for external data transfers (XDATA). When not used for addressing, the DPTR Register can be used as a general purpose 16-bit data register. Very frequently, the DPTR Register is used to access XDATA using the External Direct addressing mode. The uPSD34xx has a special set of SFR registers (DPTC, DPTM) to control a secondary DPTR Register to speed memory-to-memory XDATA transfers. Having dual DPTR Registers allows rapid switching between source and destination addresses (see details in Section 11: Dual data pointers on page 47). 7.3 Program counter (PC) The PC is a 16-bit register consisting of two 8-bit registers, PCL and PCH. This counter indicates the address of the next instruction in program memory to be fetched and executed. A reset forces the PC to location 0000h, which is where the reset jump vector is stored. 7.4 Accumulator (ACC) This is an 8-bit general purpose register which holds a source operand and receives the result of arithmetic operations. The ACC Register can also be the source or destination of logic and data movement operations. For MUL and DIV instructions, ACC is combined with 28/293 uPSD34xx 8032 MCU registers the B Register to hold 16-bit operands. The ACC is referred to as “A” in the MCU instruction set. 7.5 B register (B) The B Register is a general purpose 8-bit register for temporary data storage and also used as a 16-bit register when concatenated with the ACC Register for use with MUL and DIV instructions. 7.6 General purpose registers (R0 - R7) There are four banks of eight general purpose 8-bit registers (R0 - R7), but only one bank of eight registers is active at any given time depending on the setting in the PSW word (described next). R0 - R7 are generally used to assist in manipulating values and moving data from one memory location to another. These register banks physically reside in the first 32 locations of 8032 internal DATA SRAM, starting at address 00h. At reset, only the first bank of eight registers is active (addresses 00h to 07h), and the stack begins at address 08h. 7.7 Program status word (PSW) The PSW is an 8-bit register which stores several important bits, or flags, that are set and cleared by many 8032 instructions, reflecting the current state of the MCU core. Figure 12 on page 30 shows the individual flags. 7.7.1 Carry flag (CY) This flag is set when the last arithmetic operation that was executed results in a carry (addition) or borrow (subtraction). It is cleared by all other arithmetic operations. The CY flag is also affected by Shift and Rotate Instructions. 7.7.2 Auxiliary carry flag (AC) This flag is set when the last arithmetic operation that was executed results in a carry into (addition) or borrow from (subtraction) the high-order nibble. It is cleared by all other arithmetic operations. 7.7.3 General purpose flag (F0) This is a bit-addressable, general-purpose flag for use under software control. 7.7.4 Register bank select flags (RS1, RS0) These bits select which bank of eight registers is used during R0 - R7 register accesses (see Table 4) 7.7.5 Overflow flag (OV) The OV flag is set when: an ADD, ADDC, or SUBB instruction causes a sign change; a MUL instruction results in an overflow (result greater than 255); a DIV instruction causes a divide- 29/293 8032 MCU registers uPSD34xx by-zero condition. The OV flag is cleared by the ADD, ADDC, SUBB, MUL, and DIV instructions in all other cases. The CLRV instruction will clear the OV flag at any time. 7.7.6 Parity flag (P) The P flag is set if the sum of the eight bits in the Accumulator is odd, and P is cleared if the sum is even. Table 4.

SFRs control the operating modes of the MCU core and also control the peripheral interfaces and I/O pins on the MCU Module. The SFRs can be accessed only by using the Direct Addressing method within the address range from 80h to FFh of internal 8032 SRAM. Sixteen addresses in SFR address space are both byte- and bit-addressable. The bitaddressable SFRs are noted in Table 5. 106 of a possible 128 SFR addresses are occupied. The remaining unoccupied SFR addresses (designated as “RESERVED” in Table 5) should not be written. Reading unoccupied locations will return an undefined value. Note: There is a separate set of control registers for the PSD Module, designated as csiop, and they are described in the Section 28: PSD module on page 185. The I/O pins, PLD, and other functions on the PSD Module are NOT controlled by SFRs. SFRs are categorized as follows: ● ● ● ● ● ● ● ● MCU core registers: IP, A, B, PSW, SP, DPTL, DPTH, DPTC, DPTM MCU Module I/O Port registers: P1, P3, P4, P1SFS0, P1SFS1, P3SFS, P4SFS0, P4SFS1 Standard 8032 Timer registers TCON, TMOD, T2CON, TH0, TH1, TH2, TL0, TL1, TL2, RCAP2L, RCAP2H Standard Serial Interfaces (UART) SCON0, SBUF0, SCON1, SBUF1 Power, clock, and bus timing registers PCON, CCON0, CCON1, BUSCON Hardware watchdog timer registers WDKEY, WDRST Interrupt system registers IP, IPA, IE, IEA Prog.

Impact On Application Idle mode cannot be used with USB. Workaround Revision A - None identified at this time. Revision B - Corrected in silicon so that a USB interrupt that occurs will bring the MCU out of idle mode. 34.2 USB Reset Interrupt Description When the MCU clock prescaler is set to a value other than fMCU = fOSC (no division), a reset signal on the USB does not cause a USB interrupt to be generated. Impact On Application An MCU clock other than that equal to the frequency of the oscillator cannot be used. Workaround Revision A - The CPUPS field in the CCON0 register must be set to 000b (default after reset). The 3400 USB firmware examples set CCON0 register to 000b. Revision B - Corrected in silicon so that when an MCU clock prescaler is used, a reset signal on the USB does generate an interrupt. 34.3 USB Reset Description A USB reset does not reset the USB SIE's registers. Impact On Application A USB reset does not reset the USB SIE's registers as does a power-on or hardware reset. 287/293 Important notes uPSD34xx Workaround Revision A and B - When a USB reset is detected, the USB SIE's registers must be initialized appropriately by the firmware. The 3400 USB firmware examples clear USB SIE's registers if USB reset is detected. 34.4 Data Toggle Description The data toggle bit is read only. Impact On Application The IN FIFO data toggle bit is controlled exclusively by the USB SIE; therefore, it is not possible to change the state of the data toggle bit by firmware. Workaround Revision A - For cases where the data toggle bit must be reset, such as after a Clear Feature/Stall request, sending the subsequent data on that endpoint twice results in getting the data toggle bit back to the state that it should be. Revision B - A change in silicon was made so that the data toggle bit is reset by disabling and then enabling the respective endpoint's FIFO. 34.5 USB FIFO Accessibility Description The USB FIFO is only accessible by firmware and not by a JTAG debugger. Impact On Application Using a JTAG debugger, it is not possible to view the USB FIFO's contents in a memory dump window. Workaround Revision A and B - None identified at this time. 34.6 Erroneous Resend of Data Packet Description When a data packet is sent the respective IN FIFO busy bit is not automatically cleared by the USB SIE. This can cause a data packet to be erroneously resent to the host in response to an IN PID immediately after the first correct transmission of this data packet. Impact On Application Since the Data Toggle in the retransmitted data packet is toggled from when the data was first sent, the host will treat this packet as valid. If the identified workaround is not 288/293 uPSD34xx Important notes implemented then this extra and unexpected data packet would result in a communication breakdown. Workaround Revision A and B - In the USB ISR, when an INx (x = the endpoint number of the IN FIFO) interrupt is detected, the IN FIFOs respective busy bit should be unconditionally cleared. The uPSD3400 USB firmware implements this workaround. 34.7 IN FIFO Pairing Operation Description When FIFO pairing is used on IN endpoints, an erroneous resend of a data packet may occur. See the "Erroneous Resend of Data Packet" note as it also applies when IN FIFO pairing is used. Impact On Application See the "Erroneous Resend of Data Packet" note as the impact is the same when IN FIFO pairing is used. Workaround Revision A and B - See the "Erroneous Resend of Data Packet" note as the workaround is the same when IN FIFO pairing is used. 34.8 OUT FIFO Pairing Operation Description When data packets are received from the host and FIFO pairing is used, the paired FIFOs may get out of order. Impact On Application The received data packets are read out of order compared to the way they were sent from the host. If the workaround is not implemented, the out of order packets would result in a communication breakdown. Workaround Revision A and B - In the USB ISR, when an OUTx (x = the endpoint number of the OUT FIFO) interrupt is detected, the OUT FIFOs respective busy bit should be unconditionally cleared. The uPSD3400 USB firmware implements this workaround. 34.9 Missing ACK to host retransmission of SETUP packet Description If a host does not properly receive the ACK (due to noise) from the uPSD3400 in response to a SETUP packet, it will resend the SETUP packet but the uPSD3400 will not respond with 289/293 Important notes uPSD34xx an ACK. The host will resend the SETUP packet a number of times and if an ACK is not received from the uPSD3400, the host will issue a USB reset and then enumerate it again. Upon detecting a USB reset, the uPSD3400 firmware will reset and initialize the USB SIE putting the hardware back into the reset/initialized state so that when the next SETUP packet is received, the uPSD3400 will respond with an ACK to the host. Impact On Application If this occurs during enumeration, the impact is minimal as the host will retry the enumeration. If it happens after enumeration, the communication will break down between the host application and the uPSD3400 and will need to be re-established after the uPSD3400 is reset and enumerated again. In extremely noisy environments, the uPSD3400 may not communicate well over USB with the host application. Workaround Revision A and B - None identified at this time. 34.10 MCU JTAG ID Description MCU JTAG ID changed to differentiate revision A from revision B silicon through the JTAG port. The PSD JTAG ID remains the same. Revision A MCU JTAG ID - 0x0451F041 Revision B MCU JTAG ID - 0x1451F041 Impact On Application There will be no impact on the application. The impact will be to JTAG production programming equipment that may need to distinguish between revision A and B MCU silicon if the firmware is different depending on the revision level. 34.11 PORT 1 Not 5-volt IO Tolerant Description The port P1 is shared with the ADC module and as a result Port P1 is not 5V tolerant. Impact On Application 5V devices should not be connected to port P1. Workaround Revision A and B - Peripherals or GPIO that require 5-Volt IO tolerance should be mapped to Port 3 or Port 4. 290/293 uPSD34xx Important notes 34.12 Incorrect Code Execution when Code Banks are Switched Description When a code bank is switched, the PFQ/BC contain values from the previously selected bank and are not automatically flushed and reloaded from the newly selected code bank. Impact On Application. Depending on the contents of the PFQ/BC when the code bank is switched, improper code execution may result. Workaround. The PFQ/BC must be flushed when the code bank is changed. Disabling and re-enabling the PFQ/BC will flush them. The following instructions are an example of how to flush the PFQ/BC: ANL ORL BUSCON,#03Fh BUSCON,#0C0h ;Disable PFQ/BC ;Enable PFQ/BC Bank switching is typically handled by tool vendors in a file called l51_bank.a51. The uPSD tools offered by Keil and Raisonance now include an updated version of l51_bank.a51 for the uPSD products that flushes the PFQ/BC. The most recent banking examples available from ST's website include the updated l51_bank.a51 files. 34.13 9th Received Data Bit Corrupted in UART Modes 2 and 3 Description. If the 9th transmit data bit is written by firmware into TB8 at the same time as a received 9th bit is being written by the hardware into RB8, RB8 is not correctly updated. This applies to both UART0 and UART1. Typically, the 9th data bit is used as a parity bit to check for data transmission errors on a byte by byte basis. Impact on Application. UART Modes 2 and 3 can't be used reliably in full-duplex mode. Workaround. Revision A and B - Some options include: 1. 2. 3. 4. Only use Mode 1 (8 data bits) for full-duplex communication. Use Mode 1 and a packet based communication protocol with a checksum or CRC to detect data transmission errors. Use UART0 in mode 2 or 3 for transmitting data and UART1 in mode 2 or 3 for receiving data. Use some form of handshaking to ensure that data is never transmitted and received simultaneously on a single UART configured in mode 2 or 3. 291/293 Revision history uPSD34xx 35 Revision history Table 186.
