■Timers
• Timer 0: 16-bit programmable timer/counter with capture register
Mode 0: 8-bit programmable timer with an 8-bit programmable prescaler (with two 8-bit capture registers)
× 2 channels
Mode 1: 8-bit programmable timer with an 8-bit programmable prescaler (with two 8-bit capture registers)
+ 8-bit programmable counter (with two 8-bit capture registers)
Mode 2: 16-bit programmable timer with an 8-bit programmable prescaler
(with two 16-bit capture registers)
Mode 3: 16-bit programmable counter (with 2 16-bit capture registers)
• Timer 1: 16-bit programmable timer/counter that support PWM/ toggle output
Mode 0: 8-bit programmable timer with an 8-bit prescaler (with toggle outputs)
+ 8-bit programmable timer/counter (with toggle outputs)
Mode 1: 8-bit PWM with an 8-bit prescaler × 2 channels
Mode 2: 16-bit programmable timer/counter with an 8-bit prescaler (with toggle outputs)
(toggle outputs also from the lower-order 8 bits)
Mode 3: 16-bit programmable timer with an 8-bit prescaler (with toggle outputs)
(The lower-order 8 bits can be used as PWM.)
• Timer 4: 8-bit programmable timer with a 6-bit prescaler
• Timer 5: 8-bit programmable timer with a 6-bit prescaler
• Timer 6: 8-bit programmable timer with a 6-bit prescaler (with toggle outputs)
• Timer 7: 8-bit programmable timer with a 6-bit prescaler (with toggle outputs)
• Base timer
1) The clock is selectable from the subclock (32.768kHz crystal oscillator), cycle clock (tCYC), 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 (When High-speed clock counter is used, timer 0
cannot be used).
2) Can generate output real time.
