7.5.4 One-shot pulse output mode (TAAnMD2 to TAAnMD0 bits = 011)
In the one-shot pulse output mode, 16-bit timer/event counter AA waits for a trigger when the TAAnCTL0.TAAnCE bit is
set to 1. When the valid edge of an external trigger input is detected, 16-bit timer/event counter AA starts counting, and
outputs a one-shot pulse from the TOAAn1 pin.
Instead of the external trigger, a software trigger can also be generated to output the pulse. When the software trigger
is used, the TOAAn0 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).
