„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
• 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
• Full duplex
• 7/8/9 bit data bits selectable
• 1 stop bit (2-bit in continuous data transmission)
• Built-in baudrate generator
