Timers

• Timer 0: 16-bit timer/counter with a capture register.

Mode 0: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register)

× 2-channels

Mode 1: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) + 8-bit counter

(with an 8-bit capture register)

Mode 2: 16-bit timer with an 8-bit programmable prescaler (with a 16-bit capture register)

Mode 3: 16-bit counter (with a 16-bit capture register)

• Timer 1 : 16-bit timer/counter that supports PWM/toggle outputs

Mode 0: 8-bit timer with an 8-bit prescaler (with toggle outputs) + with an 8-bit prescaler 8-bit timer/counter

(with toggle outputs)

Mode 1: 8-bit PWM with an 8-bit 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

• 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

High-speed Clock Counter

1) Can count clocks with a maximum clock rate of 20MHz (at a main clock of 10MHz).

2) Can generate output real time.

2) Built-in 8-bit baudrate generator (maximum transfer clock cycle 4/3 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)

• SIO 1: 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)
