(8) PWM output operation (PWM output from TOX00, TOX01, TOX10, and TOX11 when TOH1 output is at high
level)
A square wave is output from the TOX00, TOX01, TOX10, and TOX11 pins by combining 8-bit timer H1 and 16-bit
timers X0 and 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.
Remark For the setting of TOH1 output, see CHAPTER 9 8-BIT TIMER H1.
