Pin Descriptions
The timer has only one pin which acts as input or output based on the
timer mode as shown in

SRU Programming
Since the timer has operation modes for input (capture and external clock
mode) and output (PWM out mode), it requires bidirectional junctions.
Table 16-3 shows the required SRU routing.

Type Description
I Timer Signal. This input is active sampled during pulse
width and period capture (width capture mode) or external
event watchdog (external clock mode).
O Timer Signal. This output is active driven in pulse width
modulation (PWM out mode).
O Timer Pin Buffer Enable Output Signal. This output is only
driven in PWM out mode.
