Introducing enCoRe II USB - ‘enhanced Component Reduction.’ Cypress has leveraged its design expertise in USB solutions to advance its family of low speed USB microcontrollers, which enable peripheral developers to design new products with a minimum number of components. The enCoRe II USB technology builds on the enCoRe family. The enCoRe family has an integrated oscillator that eliminates the external crystal or resonator, reducing overall cost. Also integrated into this chip are other external components commonly found in low speed USB applications, such as pull-up resistors, wakeup circuitry, and a 3.3 V regulator. Integrating these components reduces the overall system cost. The enCoRe II is an 8-bit flash programmable microcontroller with an integrated low speed USB interface. The instruction set is optimized specifically for USB and PS/2 operations, although the microcontrollers may be used for a variety of other embedded applications. The enCoRe II features up to 20 GPIO pins to support USB, PS/2, and other applications. The IO pins are grouped into four ports (Port 0 to 3). The pins on Port 0 and Port 1 may each be configured individually while the pins on Ports 2 and 3 are configured only as a group. Each GPIO port supports high impedance inputs, configurable pull-up, open drain output, CMOS/TTL inputs, and CMOS output with up to five pins that support a programmable drive strength of up to 50 mA sink current. GPIO Port 1 features four pins that interface at a voltage level of 3.3V. Additionally, each IO pin may be used to generate a GPIO interrupt to the microcontroller. Each GPIO port has its own GPIO interrupt vector; in addition, GPIO Port 0 has three dedicated pins that have independent interrupt vectors (P0.2–P0.4). The enCoRe II features an internal oscillator. With the presence of USB traffic, the internal oscillator may be set to precisely tune to USB timing requirements (24 MHz ±1.5%). Optionally, an external 12 MHz or 24 MHz clock is used to provide a higher precision reference for USB operation. The clock generator provides the 12 MHz and 24 MHz clocks that remain internal to the microcontroller. The enCoRe II also has a 12-bit programmable interval timer and a 16-bit Free Running Timer with Capture Timer registers. In addition, the enCoRe II includes a Watchdog timer and a vectored interrupt controller. The enCoRe II has up to eight Kbytes of flash for user code and up to 256 bytes of RAM for stack space and user variables. The power on reset circuit detects logic when power is applied to the device, resets the logic to a known state, and begins executing instructions at flash address 0x0000. When power falls below a programmable trip voltage, it generates a reset or may be configured to generate an interrupt. There is a low voltage detect circuit that detects when VCC drops below a programmable trip voltage. It is configurable to generate an LVD interrupt to inform the processor about the low voltage event. Document Number: 38-08035 Rev. *T POR and LVD share the same interrupt. There is no separate interrupt for each. The Watchdog timer may be used to ensure the firmware never gets stalled in an infinite loop. The microcontroller supports 22 maskable interrupts in the vectored interrupt controller. Interrupt sources include a USB bus reset, LVR/POR, a programmable interval timer, a 1.024 ms output from the free-running timer, three USB endpoints, two capture timers, four GPIO Ports, three Port 0 pins, two SPI, a 16-bit free running timer wrap, an internal sleep timer, and a bus active interrupt. The sleep timer causes periodic interrupts when enabled. The USB endpoints interrupt after a USB transaction complete is on the bus. The capture timers interrupt when a new timer value is saved because of a selected GPIO edge event. A total of seven GPIO interrupts support both TTL or CMOS thresholds. For additional flexibility on the edge sensitive GPIO pins, the interrupt polarity is programmed as rising or falling. The free-running 16-bit timer provides two interrupt sources: the 1.024 ms outputs and the free running counter wrap interrupt. The programmable interval timer provides up to 1 sec resolution and provides an interrupt every time it expires. These timers are used to measure the duration of an event under firmware control by reading the desired timer at the start and at the end of an event, then calculating the difference between the two values. The two 8-bit capture timer registers save a programmable 8-bit range of the free-running timer when a GPIO edge occurs on the two capture pins (P0.5, P0.6). The two 8-bit captures may be ganged into a single 16-bit capture. The enCoRe II includes an integrated USB serial interface engine (SIE) that allows the chip to easily interface to a USB host. The hardware supports one USB device address with three endpoints. The USB D+ and D– pins are optionally used as PS/2 SCLK and SDATA signals so that products are designed to respond to either USB or PS/2 modes of operation. The PS/2 operation is supported with internal 5 K pull-up resistors on P1.0 (D+) and P1.1 (D–), and an interrupt to signal the start of PS/2 activity. In USB mode, the integrated 1.5 Kpull-up resistor on D– may be controlled under firmware. No external components are necessary for dual USB and PS/2 systems, and no GPIO pins need to be dedicated to switching between modes. The enCoRe II supports in system programming by using the D+ and D– pins as the serial programming mode interface. The programming protocol is not USB. Conventions In this data sheet, bit positions in the registers are shaded to indicate which members of the enCoRe II family implement the bits.

Five registers control the primary operation of the CPU core. These registers are affected by various instructions, but are not directly accessible through the register space by the user. Table 1. CPU Registers and Register Names CPU Register Flags Register Name CPU_F Program Counter CPU_PC Accumulator CPU_A Stack Pointer CPU_SP Index CPU_X The Stack Pointer Register (CPU_SP) holds the address of the current top of the stack in the data memory space. It is affected by the PUSH, POP, LCALL, CALL, RETI, and RET instructions, which manage the software stack. It is also affected by the SWAP and ADD instructions. The Flag Register (CPU_F) has three status bits: Zero Flag bit [1]; Carry Flag bit [2]; Supervisory State bit [3]. The Global Interrupt Enable bit [0] globally enables or disables interrupts. The user cannot manipulate the Supervisory State status bit [3]. The flags are affected by arithmetic, logic, and shift operations. The manner in which each flag is changed is dependent upon the instruction being executed, such as AND, OR, XOR, and others. See Table 18 on page 14. The 16-bit Program Counter Register (CPU_PC) allows direct addressing of the full 8 Kbytes of program memory space. The Accumulator Register (CPU_A) is the general purpose register, which holds the results of instructions that specify any of the source addressing modes. The Index Register (CPU_X) holds an offset value that is used in the indexed addressing modes. Typically, this is used to address a block of data within the data memory space.

Addressing Modes Examples Source Immediate ADD A 7 The immediate value of 7 is added with the Accumulator and the result is placed in the Accumulator. MOV X 8 The immediate value of 8 is moved to the X register. AND F 9 The immediate value of 9 is logically ANDed with the F register and the result is placed in the F register. The result of an instruction using this addressing mode is placed in the A register, the F register, the SP register, or the X register, which is specified as part of the instruction opcode. Operand 1 is an immediate value that serves as a source for the instruction. Arithmetic instructions require two sources; the second source is the A or the X register specified in the opcode. Instructions using this addressing mode are two bytes in length. Table 8.
