capture register

Mode 2: 16 bit timer with 8 bit programmable prescaler and 16 bit capture register

Mode 3: 16 bit counter with 16 bit capture register

- Timer1: PWM/16 bit timer/counter (with toggle output)

Mode 0: 8 bit timer (with toggle output) + 8 bit timer counter (with toggle output)

Mode 1: 2 channel 8 bit PWM

Mode 2: 16 bit timer/counter (with toggle output)

Mode 3: 16 bit timer (with toggle output) Lower order 8 bits can be used as PWM output.

- Timer4: 8-bit timer with 6-bit prescaler

- Timer5: 8-bit timer with 6-bit prescaler

- Base timer

1. The clock signal can be selected from any of the following: sub-clock (32.768kHz crystal oscillator), system

clock, and prescaler output for timer 0.

2. Interrupts can be selected to occur at one of five different times.

(6) SIO

- SIO0: 8 bit synchronous serial interface

1. LSB first/MSB first function available

2. Internal 8-bit baud-rate generator (maximum transmit clock period 4/3 TCYC)

3. Continuous automatic data communications (1 - 256 bits)

- SIO1: 8 bit asynchronous/synchronous serial interface

Mode 0: Synchronous 8 bit serial IO (2-wire or 3-wire, transmit clock 2 - 512 TCYC)

Mode 1: Asynchronous serial IO (half duplex, 8 data bits, 1 stop bit, baud rate 8 - 2048 TCYC)

Mode 2: Bus mode 1 (start bit, 8 data bits, transmit clock 2 - 512 TCYC)

Mode 3: Bus mode 2 (start detection, 8 data bits, stop detection)

- SIO2: 8 bit synchronous serial interface

1. LSB-first

2. Built in 8-bit baud-rate generator (Maximum clock period 4/3 TCYC)

3. Continuous automatic data communication (1 - 32 bytes)

(7) AD converter
