100 = Timer0 counts at every 16 counting source events
101 = Timer0 counts at every 32 counting source events
110 = Timer0 counts at every 64 counting source events
111 = Timer0 counts at every 128 counting source events
Register 7-2 TMR0CNT
– Timer0 Counter
Position 7 6 5 4 3 2 1 0
Name TMR0CNT
Default 0 0 0 0 0 0 0 0
Access R/W R/W R/W R/W R/W R/W R/W R/W
Note: Timer0 will increase in proper condition while it is enabled. It overflows when TMR0CNT = TMR0PR,
TMR
0CNT will be clear to 0x00 when overflow occurs, and the interrupt flag will be set „1‟ by hardware.
Register 7-3 TMR0PR
– Timer0 Period
Position 7 6 5 4 3 2 1 0
Name TMR0PR
Default 1 1 1 1 1 1 1 1
Access WO WO WO WO WO WO WO WO
Note: The overflow period of the timer is: T
inc-source
* T0PSR * (T0PR + 1).
Register 7-4 TMR0PWM
– Timer0 PWM duty
Position 7 6 5 4 3 2 1 0
Name TMR0PWM
Default x x x x x x x x
Access R/W R/W R/W R/W R/W R/W R/W R/W
Note: TMR0PWM is reserved in timer/counter mode. In PWM mode, it is used as duty cycle setting. In capture
mode, the value of TMR0CNT will be captured to TMR0PWM when selected event occurs.
