Section 9 8-Bit PWM Timers

9.1

Overview

The H8S/2169 or H8/2149 has an on-chip pulse width modulation (PWM) timer module with

sixteen outputs. Sixteen output waveforms are generated from a common time base, enabling

PWM output with a high carrier frequency to be produced using pulse division. The PWM timer

module has sixteen 8-bit PWM data registers (PWDRs), and an output pulse with a duty cycle of 0

to 100% can be obtained as specified by PWDR and the port data register (P1DR or P2DR).

9.1.1

Features

The PWM timer module has the following features.

• Operable at a maximum carrier frequency of 625 kHz using pulse division (at 10-MHz

operation)

• Duty cycles from 0 to 100% with 1/256 resolution (100% duty realized by port output)

• Direct or inverted PWM output, and PWM output enable/disable control
