3. Custom Command
The IC manufacturing code is required to use a Custom command. The IC manufacturing code for the MB89R118
is “08H”.
3-1. EAS command
On EAS command reception, the transponder returns the response code “5AH” repeated 6 times after the
specified flag (“00H”) if the EAS bit is “1” or returns no response if the EAS bit is “0”. The EAS command can be
executed only when the transponder is in the ready or select state.

3-2. Write EAS command
On write EAS command reception, the transponder writes the EAS bit to FRAM.
The transponder performs verification after writing and returns an error code if the writing has failed.
The EAS bit must be set to “00H” to cancel anti-theft or goods-monitoring mode. The bit must be set to “01H” to
set up the goods-monitoring mode as the EAS data.
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation
starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of ±32/fc (2.4 µs) and latest within
20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon such
reception still return its response (However, if an EOF is not sent within 38 ms, the time-out error occurs and
the transponder can receive another command) .
