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:

Port pin Timer Input alternate function. The TPOL bit in the Timer Control 1 register
selects whether the trigger occurs on the rising edge or the falling edge of the Timer
Input signal.

generates an interrupt, and resets the count value in the Timer High and Low Byte
registers to
bit also sets the polarity of the output pulse.

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.
