• Manufacturer Part Number: HD6413008F
• Description: Renesas 16-Bit Single-Chip Microcomputer H8 Family/H8/300H Series
• Manufacturer: RENESAS [Renesas Technology Corp]

8.1
The H8/3008 has built-in 16-bit timer module with three 16-bit counter channels.
8.1.1
16-bit timer features are listed below.
• Capability to process up to 6 pulse outputs or 6 pulse inputs
• Six general registers (GRs, two per channel) with independently-assignable output compare or
• Selection of eight counter clock sources for each channel:
• Five operating modes selectable in all channels:
• Phase counting mode selectable in channel 2
• High-speed access via internal 16-bit bus
• Any initial timer output value can be set
• Nine interrupt sources
input capture functions
Internal clocks: φ, φ/2, φ/4, φ/8
External clocks: TCLKA, TCLKB, TCLKC, TCLKD
⎯ Waveform output by compare match
⎯ Input capture function
⎯ Counter clearing function
⎯ Synchronization
⎯ PWM mode
Two-phase encoder output can be counted automatically.
The 16TCNTs and GRs can be accessed at high speed via a 16-bit bus.
Selection of 0 output, 1 output, or toggle output (only 0 or 1 output in channel 2)
Rising edge, falling edge, or both edges (selectable)
Counters can be cleared by compare match or input capture
Two or more timer counters (16TCNTs) can be preset simultaneously, or cleared
simultaneously by compare match or input capture. Counter synchronization enables
synchronous register input and output.
PWM output can be provided with an arbitrary duty cycle. With synchronization, up to
three-phase PWM output is possible
