9.1
The H8/3008 has a built-in 8-bit timer module with four channels (TMR0, TMR1, TMR2, and
TMR3), based on 8-bit counters. Each channel has an 8-bit timer counter (8TCNT) and two 8-bit
time constant registers (TCORA and TCORB) that are constantly compared with the 8TCNT
value to detect compare match events. The timers can be used as multifunctional timers in a
variety of applications, including the generation of a rectangular-wave output with an arbitrary
duty cycle.
9.1.1
The features of the 8-bit timer module are listed below.
• Selection of four clock sources
• Selection of three ways to clear the counters
• Timer output controlled by two compare match signals
• A/D converter can be activated by a compare match
• Two channels can be cascaded
• Input capture function can be set
• Twelve interrupt sources
The counters can be driven by one of three internal clock signals (φ/8, φ/64, or φ/8192) or an
external clock input (enabling use as an external event counter).
The counters can be cleared on compare match A or B, or input capture B.
The timer output signal in each channel is controlled by two independent compare match
signals, enabling the timer to generate output waveforms with an arbitrary duty cycle or PWM
output.
⎯ Channels 0 and 1 can be operated as the upper and lower halves of a 16-bit timer (16-bit
⎯ Channels 2 and 3 can be operated as the upper and lower halves of a 16-bit timer (16-bit
⎯ Channel 1 can count channel 0 compare match events (compare match count mode).
⎯ Channel 3 can count channel 2 compare match events (compare match count mode).
8-bit or 16-bit input capture operation is available.
There are twelve interrupt sources: four compare match sources, four compare match/input
capture sources, four overflow sources.
