10.5 Continuous Mode (001b)
In Continuous mode, the timer peripheral increments TMRn_CNT until it matches TMRn_CMP, resets TMRn_CNT to
0x0000 0001, and continues incrementing. The timer peripheral can optionally toggle the state of the timer pin at the end
of the timer period.

10.5.1 Timer Period
The timer period ends on the timer clock following TMRn_CNT = TMRn_CMP.
The timer peripheral automatically performs the following actions at the end of the timer period:
1. TMRn_CNT is reset to 0x0000 0001. The timer remains enabled and continues incrementing.
2. If the timer output is enabled, the timer pin toggles state (low to high or high to low).
3. The timer interrupt bit TMRn_INT.irq will be set. An interrupt will be generated if enabled.
