10.3.2 Initializing the Counters
The timer control register (TMRCON) has three formats: control word, counter-latch, and read-
back. When writing to TMRCON, certain bit settings determine which format is accessed.
Use the TMRCON’s control word format (Figure 10-25) to specify a counter’s count format and
operating mode. Writing the control word forces OUTn to go to an initial state that depends on
the selected operating mode.
