10.5.2 Configuration
Configure the timer for Continuous mode by performing the following steps:
1. Set TMRn_CN.ten = 0 to disable the timer.
2. Set TMRn_CN.tmode to 001b to select Continuous 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 as a timer output 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 an initial value to TMRn_CNT, if desired. This effects only the first period; subsequent timer periods always
reset TMRn_CNT= 0x0000 0001.
7. Write the compare value to TMRn_CMP.
8. Set TMRn_CN.ten = 1 to enable the timer.
The timer period is calculated using the following equation.
