APPENDIX 1.10 Mark detection function
Any motion control data and all device data can be latched at the input timing of the
mark detection signal. Also, data within a specific range can be latched by specifying
the data detection range.
The following three modes are available for execution of mark detection.
1) Continuous Detection mode
The latched data is always stored at mark detection.
Operation is the same as the high-speed reading function.

2) Specified Number of Detections mode
The latched data from a specified number of detections is stored.
Example) Number of detections: 3

The 4th detection
and later are ignored.
3) Ring Buffer mode
The latched data is stored in a ring buffer for a specified number of detections.
The latched data is always stored at mark detection.
Example) Number of detections: 4

The 5th detection
replaces the previous
