(6) Timers
- Timer0: 16 bit timer/counter with capture register
Mode 0: 2 channel 8 bit timer with programmable 8 bit prescaler and 8 bit capture register
Mode 1: 8 bit timer with 8 bit programmable prescaler and 8 bit capture register + 8 bit counter with 8 bit
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.
- 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.
(7) 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 T_CYC)
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 T_CYC)
Mode 1: Asynchronous serial IO (half duplex, 8 data bits, 1 stop bit, baud rate 8 - 2048 T_CYC)
Mode 2: Bus mode 1 (start bit, 8 data bits, transmit clock 2 - 512 T_CYC)
Mode 3: Bus mode 2 (start detection, 8 data bits, stop detection)
(8) AD converter
