„ Timers
• Timer 0 : 16-bit timer/counter with capture register
Mode 0: 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers) × 2 channels
Mode 1: 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers)
+ 8-bit counter (with two 8-bit capture registers)
Mode 2: 16-bit timer with an 8-bit programmable prescaler (with two 16-bit capture registers)
Mode 3: 16-bit counter (with 216-bit capture registers)
• Timer 1: 16-bit timer/counter that support PWM/ toggle output
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 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 oscillator), system clock, and timer 0 prescaler
output.
(2) Interrupts programmable in 5 different time schemes.
„ High-speed Clock Counter
(1) Capable of counting clocks with a maximum clock rate of 24MHz (at a main clock of 12MHz).
(2) Capable of generating 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)
• 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)
