trigger is used, the TOP00 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).
This mode is valid only in TMP0, TMP2, and TMP3 (V850E/IA4 only) (software trigger only for TMP3).
In the one-shot pulse output mode, 16-bit timer/event counter P waits for a trigger when the TPmCTL0.TPmCE bit
Instead of the external trigger, a software trigger can also be generated to output the pulse. When the software
