capture register under software control. To determine the number of events (i.e., cycles) counted, the
value in the capture register must be read.
In the following example, the TMRB0 is used to accomplish periodic interrupt generation. The
This mode is used to count events by interpreting the rising edges of the external counter clock
The up-counter (UC0) counts up on each rising clock edge. The counter value is be latched into a
Even when the timer is used for event counting, the prescaler must be programmed to run (i.e., the
TB0RUN.TB0PRUN bit must be set to 1).
