+ 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 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 7: 8-bit timer with a 6-bit prescaler (with toggle outputs)
- Base timer
1) The clock is selectable from the subclock (32.768 kHz crystal oscillator), 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

2) Built-in 8-bit baudrate generator (maximum transfer clock cycle = 4/3 tCYC)
3) Automatic continuous data transmission (1 to 256 bits)
• 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)
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)
• SIO2: 8 bit synchronous serial interface
1) LSB first mode
2) Built-in 8-bit baudrate generator (maximum transfer clock cycle = 4/3 Tcyc)
3) Automatic continuous data transmission (1 to 32 bytes)
