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. Using the internal clock source, there is only 1 reference time-base for Timer/Event Counter 0. The internal clock source is coming from fSYS/4. The external clock input allows the user to count exter- nal events, measure time intervals or pulse widths. Using the internal clock source, there is only 1 reference time-base for Timer/Event Counter 1. The internal clock source is coming from fSYS/4. The external clock input allows the user to count external events, measure time intervals or pulse widths. There are 2 registers related to the Timer/Event Counter 0; TMR0 ([0DH]), TMR0C ([0EH]). Two physical regis- ters are mapped to TMR0 location; writing TMR0 makes the starting value be placed in the Timer/Event Counter 0 preload register and reading TMR0 gets the contents of the Timer/Event Counter 0. The TMR0C is a timer/event counter control register, which defines some options. |
