Section 8 16-Bit Integrated Timer Unit (ITU)
8.1 Overview
The H8/3032 Series has a built-in 16-bit integrated timer-pulse unit (ITU) with five 16-bit timer
channels.
8.1.1 Features
ITU features are listed below.
⢠Capability to process up to 12 pulse outputs or 10 pulse inputs
⢠Ten general registers (GRs, two per channel) with independently-assignable output compare
or input capture functions
⢠Selection of eight counter clock sources for each channel:
Internal clocks: ø, ø/2, ø/4, ø/8
External clocks: TCLKA, TCLKB, TCLKC, TCLKD
⢠Five operating modes selectable in all channels:
â Waveform output by compare match
Selection of 0 output, 1 output, or toggle output (only 0 or 1 output in channel 2)
â Input capture function
Rising edge, falling edge, or both edges (selectable)
â Counter clearing function
Counters can be cleared by compare match or input capture
â Synchronization
Two or more timer counters (TCNTs) can be preset simultaneously, or cleared
simultaneously by compare match or input capture. Counter synchronization enables
synchronous register input and output.
