16.9.2 Compare Mode Configuration
Configure the timer for Compare mode by doing the following:
1. Set TMRn_CN.ten = 0 to disable the timer.
2. Set TMRn_CN.tmode to 011b to select Compare mode.
3. Set TMRn_CN.pres3:TMRn_CN.pres to set the prescaler that determines the timer frequency.
4. If using the timer pin:
a. Configure the pin for the timer output alternate function and configure the electrical characteristics as
needed.
b. Set TMRn_CN.tpol to match the desired (inactive) state.
5. If using the timer interrupt, enable the interrupt and set the interrupt priority.
6. Write the initial value to TMRn_CNT. This effects only the first period as the counter increments continuously,
rolling over to 0x0000 0000 and continuing.
7. Write the compare value to TMRn_CMP.
8. Set TMRn_CN.ten = 1 to enable the timer.
The Compare Mode timer period is calculated using Equation 16-10.
