Timer/Event Counter

Two timer/event counters (TMR0, TMR1) are imple-

mented in the microcontroller. The Timer/Event Counter

0 contains an 8-bit programmable count-up counter and

the clock may comes from an external source or from

fSYS/4.

The Timer/Event Counter 1 contains an 16-bit program-

mable count-up counter and the clock may come from

an external source or from the system clock divided by

4.

To enable/disable timer 0 counting (0=disabled; 1=enabled)

To define the operating mode

01=Event count mode (external clock)

10=Timer mode (internal clock)

11=Pulse width measurement mode
