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
