Timers
• Timer 0: 16-bit timer that supports PWM/toggle outputs
<1> With 5-bit prescaler
<2> 8-bit PWM × 2 / 8-bit timer + 8-bit PWM split mode selectable
<3> Clock source selectable from system clock, OSC0, OSC1, and internal RC oscillator
• Timer 1: 16-bit timer with a capture register
<1> With 5-bit prescaler
<2> Can be divided into 8-bit timer × 2 channels
<3> Clock source selectable from system clock, OSC0, OSC1, and internal RC oscillator
• Timer 3: 16-bit timer that supports PWM/toggle outputs
<1> With 8-bit prescaler
<2> 8-bit timer × 2 channels / 8-bit timer + 8-bit PWM split mode selectable
<3> Clock source selectable from system clock, OSC0, OSC1, and external events
• Timer 4: 16-bit timer that supports toggle output
<1> Clock source selectable from system clock and prescaler 0
• Timer 5: 16-bit timer that supports toggle output
<1> Clock source selectable from system clock and prescaler 0
* The prescaler 0 consists of 4 bits and its clock source is selectable from the system clock, OSC0, and OSC1.
• Base timer
<1> The clock can be selected from OSC0 (32.768kHz crystal oscillator) and the frequency-divided output of the
system clock.
<2> Interrupts can be generated in 7 time schemes.
Realtime clock (RTC)
<1> Calendar function from January 1, 2000 to December 31, 2799 (with automatic leap year compensation)
<2> Independent counter configuration for century, year, month, day, hour, minute, and second
<3> Programmable count clock correction function
