counting, and outputs a one-shot pulse from the TOAm1 pin.
the software trigger is used, the TOAm0 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 TAA2, TAA3 (V850E/IG3 only), and TAA4.
In the one-shot pulse output mode, 16-bit timer/event counter AA waits for a trigger when the TAAmCTL0.TAAmCE
Instead of the external trigger input (TIAm0), a software trigger can also be generated to output the pulse. When
