13.11 WRITE ISO 11785 (custom command)
[μ, Advanced, Advanced+]
Upon reception of this command without error, the transponder IC (in Ready state) writes
128-bit of ISO 11785 TTF data into suitable reserved memory block and report the
success of the operation in the response. The user does not have to attend whether the
data is compliant to ISO 11785 or not. The command data block is sent exactly the same
way as it is sent by the transponder IC in TTF mode (Header, 64-bit ID, CRC…) after
entering the field again.
There are two different command codes one for locking the TTF area after successful
write command and one without locking.
The command must be completed by a reset of the IC. After entering the RF field the
ISO 11785 data is sent when the transponder is in ISO 11785 state.
