Edge
In the one-shot pulse output mode, 16-bit timer/event counter P waits for a
trigger when the TPnCTL0.TPnCE bit is set to 1. When the valid edge of an
external trigger input is detected, 16-bit timer/event counter P starts counting,
and outputs a one-shot pulse from the TOPn1 pin.
Instead of the external trigger, a software trigger can also be generated to
output the pulse. When the software trigger is used, the TOPn0 pin outputs the
active level while the 16-bit counter is counting, and the inactive level when the
counter is stopped (waiting for a trigger).
