• Manufacturer Part Number: HD6412373R
• Description: Renesas 16-Bit Single-Chip Microcomputer H8S Family/H8S/2300 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

This LSI has an on-chip 8-bit timer module with two channels operating on the basis of an 8-bit
counter. The 8-bit timer module can be used to count external events and be used as a
multifunction timer in a variety of applications, such as generation of counter reset, interrupt
requests, and pulse output with an arbitrary duty cycle using a compare-match signal with two
registers.
13.1
• Selection of four clock sources
• Selection of three ways to clear the counters
• Timer output control by a combination of two compare match signals
• Provision for cascading of two channels (TMR_0 and TMR_1)
• Three independent interrupts
• A/D converter conversion start trigger can be generated
TIMH260A_000020020400
The counters can be driven by one of three internal clock signals (φ/8, φ/64, or φ/8192) or an
external clock input
The counters can be cleared on compare match A or B, or by an external reset signal
The timer output signal in each channel is controlled by a combination of two independent
compare match signals, enabling the timer to generate output waveforms with an arbitrary duty
cycle or PWM output
Operation as a 16-bit timer is possible, using TMR_0 for the upper 8 bits and TMR_1 for the
lower 8 bits (16-bit count mode)
TMR_1 can be used to count TMR_0 compare matches (compare match count mode)
Compare match A and B and overflow interrupts can be requested independently
