Section 10 PWM Timers
10.1
Overview
The H8/3337 Series and H8/3397 Series have an on-chip pulse-width modulation (PWM) timer
module with two independent channels (PWM0 and PWM1). Both channels are functionally
identical. Each PWM channel generates a rectangular output pulse with a duty cycle of 0 to 100%.
The duty cycle is specified in an 8-bit duty register (DTR).
