TAAmCTL0.TAAmCE bit is set to 1. When the valid edge of an external trigger input (TIAm0) is detected, 16-bit
timer/event counter AA starts counting, and outputs a PWM waveform from the TOAm1 pin.
software trigger, a PWM waveform with a duty factor of 50% that has the set value of the TAAmCCR0 register + 1 as
half its cycle can also be output from the TOAm0 pin.

This mode is valid only in TAA2, TAA3 (V850E/IG3 only), and TAA4.
In the external trigger pulse output mode, 16-bit timer/event counter AA waits for a trigger when the
Pulses can also be output by generating a software trigger instead of using the external trigger. When using a
