Cyclic Redundancy Check (CRC)
When a frame is received, reception of correct data--that is, the characters making up the frame is assumed
only when the value of the cyclic redundancy check (CRC) code is valid. For error-checking purposes, a 2-byte
CRC code value is inserted between data and the EOF signal.
The value of CRC code is required from all the data contained between the SOF and CRC field in each frame.
Method of calculation is provided in ISO/IEC 13239. The initial value of the CRC code provided in ISO/IEC
15693-3 is “FFFF
H
”.
The CRC code is transferred, beginning with the lowest-order bit in the lowest-order byte.

Electronic Article Surveillance (EAS) status
EAS status is 1 bit data (LSB side) , which is stored in the system area of memory (FRAM) . The initial value is
“1”. EAS bit “1” means goods-monitoring status, and EAS bit “0” means that goods-monitoring status is cleared.
EAS status can be written by Write EAS command and can be checked “FB
H
” block (refer to “
■
MEMORY MAP”)
by Read commands such as Read Signal Block command.
Together with Gate type reader/writer, EAS command can support anti-theft security functions.
