15.3.5
TERs are used to report events recognized by the timer. On recognition of an event, the timer sets the
appropriate TERn bit, regardless of the corresponding interrupt enable bits (ORI and CE) in the TMRn.
Writing a 1 to a bit clears it; writing 0 has no effect. Both bits must be cleared before the timer can negate
the request to the interrupt controller. Both bits may be cleared simultaneously.
