7.5.8 WRITE PAGE
After a HITAG S Transponder was selected by the corresponding SELECT (UID)
command (or SELECT (UID) and CHALLENGE for Authentication Mode) a write
operation of data onto the memory can be carried out. Least significant Byte is always
transmitted first. E.g. in order to change the configuration page the byte CON0 would have
to be transmitted first.
After transmitting the WRITE PAGE command, the Page address PADR (8 Bits) and the
8 bit Cyclic Redundancy Check (CRC 8), the HITAG S Transponder responds with the
SOF and an acknowledge (ACK) to confirm the reception of a correct WRITE PAGE
command. After the waiting time t
the programming time t
acknowledge to confirm correct programming.
