6. APPLICATION FUNCTIONS
6.30.4 Operation example
(1) Continuous detection mode
The mark detection counter is incremented at mark detection. After mark detection, read the mark detection
data and update the read complete buffer number. When mark detection data is not read before the next
mark detection, a mark detection write/read error (operation alarm A6, detail No.01) occurs, followed by a
rapid stop.
Example: When both ON/OFF edges are enabled.

POINT
• Mark detection interrupt cannot be used for interface mode. The mark
detection counter can be continuously monitored by polling.
API LIBRARY
• Use the sscGetMarkDetectionData function to get mark detection data.
• The read number setting for the read complete buffer number is conducted
within the sscGetMarkDetectionData function therefore user program
processing is not required.
• Use the sscGetMarkDetectionCounter function to get the mark detection
counter.
• When using mark detection interrupt, use the sscWaitIntEvent function and
wait until interrupt is output. If not using mark detection interrupt, use polling.
When using polling, use the sscGetMarkDetectionCounter function to
periodically check that the mark detection counter is updated.
