Timers
• Timer 0: 16-bit timer that supports PWM/toggle outputs
1) 5-bit prescaler
2) 8-bit PWM × 2, 8-bit timer + 8-bit PWM mode selectable
3) Clock source selectable from system clock, OSC0, OSC1, and internal RC oscillator
• Timer 1: 16-bit timer with capture registers
1) 5-bit prescaler
2) May be divided into 2 channels of 8-bit timer
3) Clock source selectable from system clock, OSC0, OSC1, and internal RC oscillator
• Timer 2: 16-bit timer with capture registers
1) 4-bit prescaler
2) May be divided into 2 channels of 8-bit timer
3) Clock source selectable from system clock, OSC0, OSC1, and external events
• Timer 3: 16-bit timer that supports PWM/toggle outputs
1) 8-bit prescaler
2) 8-bit timer × 2ch or 8-bit timer + 8-bit PWM mode selectable
3) Clock source selectable from system clock, OSC0, OSC1, and external events
• Timer 4: 16-bit timer that supports toggle outputs
1) Clock source selectable from system clock and prescaler 0
• Timer 5: 16-bit timer that supports toggle outputs
1) Clock source selectable from system clock and prescaler 0
* Prescaler 0 and 1 are consisted of 4 bits and can choose their clock source from OSC0 or OSC1.
• Base timer
1) Clock may be selected from OSC0 (32.768kHz crystal oscillator) and frequency-divided output of system clock.
2) Interrupts can be generated in 7 timing schemes.
Real time clock
1) Calender with Jan. 1, 2000 to Dec.31, 2799 including automatic leap year calculation function.
2) Consisted of Independent second- minute-hour-day-month-year-century counters.
3) Programmable count-clock calibration function.
