The counter board has the following functions when the count value became the specified value
- Generates interrupt (Notified with Window message or callback function)
- Outputs one-short pulse (Control output signal)
- Presets the count value to a specified value (for devices with sampling function)
- Clears the count value to zero (for devices with sampling function)
The count match interrupt can be notified to an application as a message or a callback. For using the count match, there are count comparison registers on the hardware, set the comparison registers and notification message with the CntNotifyCountUp function.
The number of comparison registers becomes one or two (for devices with sampling function) for each channel.
