10.1
The H8/3048B Group has a built-in 16-bit integrated timer unit (ITU) with five 16-bit timer
channels.
When the ITU is not used, it can be independently halted to conserve power. For details see
section 20.6, Module Standby Function.
10.1.1
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: , /2, /4, /8
External clocks: TCLKA, TCLKB, TCLKC, TCLKD
Five operating modes selectable in all channels:
Phase counting mode selectable in channel 2
Two-phase encoder output can be counted automatically.
Waveform output by compare match
Selection of 0 output, 1 output, or toggle output (only 0 or 1 output in channel 2)
Input capture function
Rising edge, falling edge, or both edges (selectable)
Counter clearing function
Counters can be cleared by compare match or input capture
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.
PWM mode
PWM output can be provided with an arbitrary duty cycle. With synchronization, up to
five-phase PWM output is possible
