(7) PWM output operation (PWM output from TOX1n when TOH1 output is at high level)
A square wave is output from the TOX1n pin by combining 8-bit timer H1 and 16-bit timer X1, only when the TOH1
output is at high level.
See (1) PWM output operation (single output) through (4) PWM output operation (TMX0 and TMX1
synchronous start mode) for the setting of outputting a square wave.
Remarks 1. n = 0, 1
2. For the setting of TOH1 output, see CHAPTER 9 8-BIT TIMER H1.

Performs PWM output from TOXmn pin
when TOH1 output is high level.
0: Using the TOX0n output gate function by
TOH1 output is prohibited.
1: Using the TOX0n output gate function by
TOH1 output is enabled.
0: Starts counting when TX0TMC bit = 1.
1: Starts timer counting when TX0TMC bit = 1
and INTP0 rising edge is detected.
