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- tem clock/4). For TMR1, the internal source is 32768Hz. 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. |
