Triggered ONE-SHOT Mode
In Triggered ONE-SHOT mode, the Timer operates as follows:
1. The Timer idles until a trigger is received. The Timer trigger is taken from the GPIO
2. Following the trigger event, the Timer counts timer clocks up to the 16-bit Reload
3. On reaching the Reload value, the Timer outputs a pulse on the Timer Output pin,
4. The Timer now idles until the next trigger event.
In Triggered ONE-SHOT mode, the timer clock always provides the timer input. The
timer period is given by the following equation:

Comment
TMODE[3:0] = 1011B selects Triggered ONE-SHOT mode.
TICONFIG[1:0] = 11B enables interrupts on Timer reload only.
CSC = 0 selects the Timer Input (Trigger) from the GPIO pin.
PWMD[2:0] = 000B has no effect.
INPCAP = 0 has no effect.
TEN = 0 disables the timer.
TPOL = 0 enables triggering on rising edge of Timer. Input and sets
PRES[2:0] = 000B sets prescaler to divide by 1.
TCLKS = 1 sets 32 kHz peripheral clock as the Timer clock source.
Timer reload value = ABCDH.
. The period of the output pulse is a single timer clock. The TPOL
Timer Out signal to 0.
