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
f
SYS
/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.
