10.4 One-Shot Mode (000b)
In One-shot mode the timer peripheral increments TMRn_CNT until it matches TMRn_CMP and then stops incrementing
and disables the timer. The timer can optionally output a pulse on the timer pin at the end of the timer period. In this
mode, the timer must be re-enabled to start another one-shot mode event.

10.4.1 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.
2. The timer is disabled by setting TMRn_CN.ten = 0.
3. If the timer output is enabled, the timer pin is driven to its active state for one timer clock. It then returns to its
inactive state.
4. The timer interrupt bit TMRn_INT.irq will be set. An interrupt will be generated if enabled.
