Timer Module
Timers 0 and 1 may output a signal on the timer outputs (TOUT0 or TOUT1) when the reference value is
reached, as selected by the output mode bit, TMR[OM]. This signal can be an active-low pulse or a toggle
of the current output, under program control.
The TCAPs are used to latch counter values when the corresponding input capture edge detector detects a
defined transition (of TIN0, TIN1, URT0_RxD, or URT1_RxD). The type of transition triggering the
capture is selected by the capture edge bits, TMR[CE].A capture or reference event sets the TER bit and
generates a maskable interrupt.
