„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 a 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 sub-clock (32.768kHz crystal oscillation/slow RC oscillation), system clock, and
prescaler output from timer 0.
2) Interrupts are programmable in 5 different time schemes.
• Real time clock (RTC)
1) Used with a base timer, it can be used as a century + year + month + day + hour + minute + second counter.
2) Calendar counts up to December 31, 2799 with automatic leap-year calculation.
„High-speed Clock Counter
• Count clocks with a maximum clock rate of 24MHz (when main clock is 12MHz)
• Real-time output
