TTmCTL0.TTmCE bit is set to 1. When the valid edge of an external trigger input (EVTTm) is detected, 16-bit
timer/event counter T starts counting, and outputs a PWM waveform from the TOTm1 pin. A PWM waveform with a
duty factor of 50% that has the set value of the TTmCCR0 register + 1 as half its cycle can also be output from the
TOTm0 pin.

This mode is valid only in TMT0 (V850E/IG3 only) and TMT1.
In the external trigger pulse output mode, 16-bit timer/event counter T waits for a trigger when the
Pulses can also be output by generating a software trigger instead of using the external trigger.
