APPENDIX 2 PROCESSING TIME (REFERENCE)
The processing time is the time from the moment the ID command execution request
(RYn4) is turned ON to the moment ID command complete (RXn4) turns ON.
The processing time is shown below for each type of ID tags.
For link refresh time and link scan time details, refer to the user's manual of the master
module.
