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) + 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

• Timer 5 : 8-bit timer with a 6-bit prescaler

• Timer 6 : 8-bit timer with a 6-bit prescaler (with toggle outputs)

• Timer 7 : 8-bit timer with a 6-bit prescaler (with toggle outputs)

• 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

SIO

• SIO0 : 8-bit synchronous serial interface

1) LSB first/MSB first mode selectable

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)

• 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)

UART
