Timer/Event Counter
Two timer/event counters (TMR0, TMR1) are imple-
mented in the telephone controller series. The
Timer/Event Counter 0 and Timer/Event Counter 1 con-
tain 16-bits programmable count-up counter and the
clock may come from an external or internal source. For
TMR0, the internal source is the instruction clock (sys-
temclock/4).ForTMR1,theinternalsourceis32768Hz.
Using the 32768Hz clock or instruction clock, there is
only one reference time-base. The external clock input
allows the user to count external events, measure time
intervals or pulse width, or generate an accurate time
base.
There are 3 registers related to the Timer/Event Counter
0; TMR0H, TMR0L and TMR0C. Writing TMR0L only
writes the data into a low byte buffer, but writing TMR0H
simultaneously writes the data along with the contents
of the low byte buffer into the Timer/Event Counter 0
preload register (16-bit). The Timer/Event Counter 0
preload register is changed by writing TMR0H opera-
tions. Writing TMR0L will keep the Timer/Event Counter
0 preload register unchanged.
