Description
original Hitachi CMOS microcomputer unit (MCU)
Manufacturer
HITACHI [Hitachi Semiconductor]
Datasheet
Section 12 PWM Timer
12.1 Overview
The H8/532 has an on-chip pulse-width modulation (PWM) timer module with three independent
channels (PWM1, PWM2, and PWM3). All three channels are functionally identical. Using an
8-bit timer counter, each PWM channel generates a rectangular output pulse with a duty factor of
0 to 100%. The duty factor is specified in an 8-bit duty register (DTR).
12.1.1 Features
The PWM timer module has the following features:
• Selection of eight clock sources
• Duty factors from 0 to 100% with 1/250 resolution
• Output with positive or negative logic
12.1.2 Block Diagram
Figure 12-1 shows a block diagram of one PWM timer channel.
