„Timers
• Timer 0: 16 bit timer / counter with 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 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 output)
• Timer 7: 8-bit timer with a 6-bit prescaler (with toggle output)
• 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
1) Can count clocks with a maximum clock rate of 20MHz (at a main clock of 10MHz).
2) Can generate output real-time.
„Serial Interface
• SIO 0: 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)
• 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)
