Count match
This product can generate an interrupt, output an external one-shot pulse, preset the counter, and clear it
to zero when the count value matches the value in comparison register 0 or 1.
This product has two comparison registers for each channel to compare the count value with. If two or
more registers are required, reprogram the setting using software. When you have two comparison
registers available at the same time, the upper and lower values can be set.

Given below are application examples using the count match feature.
<Example 1> Move count values 100 - 200 in both ways. When the count value falls below 90 or
exceeds 210, a one-shot pulse is output to an external device.

:
Count match 0 or Count match 1

Channel 0 Comparison reg
ister 0= 90
Channel 0 Preset register = 100
Event at (2) (Agrees with comparison register 1)
- A one-shot pulse is output with count value = comparison register 1.
Event at (1) (Agrees with comparison register 0)
- A one-shot pulse is output with count value = comparison register 0.
