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 an 8-bit prescaler (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 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 are programmable in 5 different time schemes
High-speed Clock Counter
Can count clocks with a maximum clock rate of 20MHz (at a main clock of 10MHz).
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)
■UART1
Full duplex
7/8/9 bit data bits selectable
1 stop bit (2-bit in continuous data transmission)
Built-in baudrate generator
