(5) PWM output operation (PWM output from TOX0n when TOH1 output is at high level)
A square wave is output from the TOX0n pin by combining 8-bit timer H1 and 16-bit timer X0, 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.

Dual output
Using the TOX0n output gate function by
TOH1 output is enabled.
