RF TAG OVERWRITE COUNT CONTROL Query with an Addition Specification
The overwrite count control area consists of 4 bytes from the specified start address. The increment
value is added to the overwrite count and then written to this area. When the value reaches 100,000
(i.e., 0186A0 hex), a warning code is returned. You can read the overwrite count control area with a
read query. If the control area data is already 100,000, the control area value will not be refreshed,
and a warning code will be returned as a response. When the refresh count is set to 0000 hex, the
count will not be updated, and only an overwrite count check will be performed.
