Timers
• Timer 0: 16-bit timer/counter with two capture registers.
Mode 0: 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers)
× 2 channels
Mode 1: 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers)
+ 8-bit counter (with two 8-bit capture registers)
Mode 2: 16-bit timer with an 8-bit programmable prescaler (with two 16-bit capture registers)
Mode 3: 16-bit counter (with two 16-bit capture registers)
• Timer 1: 16-bit timer/counter that supports PWM/toggle outputs
Mode 0: 8-bit timer with an 8-bit prescaler (with toggle outputs) + 8-bit timer/
counter with an 8-bit prescaler (with toggle outputs)
Mode 1: 8-bit PWM with an-8bit prescaler
× 2 channels
Mode 2: 16-bit timer/counter with an 8-bit prescaler (with toggle outputs)
(toggle outputs also possible from the lower-order 8 bits)
Mode 3: 16-bit timer with an 8-bit prescaler (with toggle outputs)
(The lower-order 8 bits can be used as PWM.)
• Timer 4: 8-bit timer with a 6-bit prescaler
• Timer 5: 8-bit timer with a 6-bit prescaler
• Timer 6: 8-bit timer with a 6-bit prescaler (with toggle output)
• Timer 7: 8-bit timer with a 6-bit prescaler (with toggle output)
• Base timer
1) The clock is selectable from the subclock (32.768kHz crystal oscillation), system clock, and timer 0 prescaler
output.
2) Interrupts programmable in 5 different time schemes
SIO
• SIO0: Synchronous serial interface
1) LSB first/MSB first mode selectable
2) Transfer clock cycle: 4/3 to 512/3 tCYC
3) Automatic continuous data transmission
(1 to 256 bits, specifiable in 1 bit units, suspension and resumption of data transmission possible in 1 byte units)
• SIO1: 8-bit asynchronous/synchronous serial interface
Mode 0: Synchronous 8-bit serial I/O (2- or 3-wire configuration, 2 to 512 tCYC transfer clocks)
Mode 1: Asynchronous serial I/O (half-duplex, 8 data bits, 1 stop bit, 8 to 2048 tCYC baudrates)
Mode 2: Bus mode 1 (start bit, 8 data bits, 2 to 512 tCYC transfer clocks)
Mode 3: Bus mode 2 (start detect, 8 data bits, stop detect)
• SIO4: Synchronous serial interface
1) LSB first/MSB first mode selectable
2) Transfer clock cycle: 4/3 to 1020/3 tCYC
3) Automatic continuous data transmission (1 to 4096 bytes, specifiable in 1 byte units, suspension and resumption
of data transmission possible in 1 byte or 2 bytes units)
4) Auto-start-on-falling-edge function
5) Clock polarity selectable
6) CRC16 calculator circuit built in
