6.5 PWM Output Function
6.5.1 Overview
PWM output function
With the F173 (PWMH) instruction, the pulse width modulation output of the specified duty ratio is
obtained.
System register setting
When using the PWM output function, set the channel CH0 and CH2 with system registers 400 and 401
to “High-speed counter not used”.
