TIMH220B_000020020700
The H8S/2268 Group has an on-chip 8-bit timer module with four channels (TMR_0, TMR_1,
TMR_2 and TMR_3) operating on the basis of an 8-bit counter and an 8-bit reload timer with four
channels (TMR_4). The H8S/2264 Group has an on-chip 8-bit timer module with two channels
(TMR_0 and TMR_1) operating on the basis of an 8-bit counter.
11.1
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.
11.1.1
• Selection of clock sources
• Selection of three ways to clear the counters
• Timer output controlled by two compare-match signals
• Cascading of the two channels
• Multiple interrupt sources for each channel
• Generation of A/D conversion start trigger
• Module stop mode can be set
Note: * Supported only by the H8S/2268 Group.
Selected from three internal clocks (φ/8, φ/64, and φ/8192) and an external clock.
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 two independent compare-match
signals, enabling the timer to be used for various applications, such as the generation of pulse
output or PWM output with an arbitrary duty cycle.
The module can operate as a 16-bit timer using channel 0 (channel 2 * ) as the upper half and
channel 1 (channel 3 * ) as the lower half (16-bit count mode).
Channel 1 (channel 3 * ) can be used to count channel 0 (channel 2 * ) compare-match
occurrences (compare-match count mode).
Two compare-match interrupts and one overflow interrupt can be requested independently.
Channel 0 compare-match signal can be used as the A/D conversion start trigger.
At initialization, the 8-bit timer operation is halted. Register access is enabled by canceling the
module stop mode.
