10.6.2 Configuration
Configure the timer for Counter mode by doing the following:
1. Set TMRn_CN.ten = 0 to disable the timer.
2. Set TMRn_CN.tmode to 010b to select Counter mode.
3. Configure the timer pin:
a. Configure the pin as a timer input and configure the electrical characteristics as needed.
b. Set TMRn_CN.tpol to match the desired initial (inactive) state.
4. If using the timer interrupt, enable the interrupt and set the interrupt priority.
5. Write an initial value to TMRn_CNT, if desired. This effects only the first period; subsequent timer periods always
reset TMRn_CNT= 0x0000 0001.
6. Write the compare value to TMRn_CMP.
7. Set TMRn_CN.ten = 1 to enable the timer.
In Counter mode, the number of timer input transitions since timer start is calculated using the following equation:
