Read User Zone Command with Integrated MAC [$c2] [88RF]
The Read User Zone command with Integrated MAC reads data from the currently selected User Zone on 88RF
PICCs. This command can only be used when the Authentication or Encryption Communication Security mode is
active.
The Read User Zone command with Integrated MAC reads data from the 88RF device's currently selected User Zone
and also returns the cryptographic checksum. If the RCS bit of the DCR register is set to 1b, then the cryptographic
engine is reset after the checksum is read.
engine is not reset by this command.
The data byte address is internally incremented as each byte is read from memory. Reading beyond the end of the
current User Zone is prohibited. Only PICCs in the Active State are permitted to answer this command. If the
Authentication or Encryption Communication Security mode is not active, then a NACK response is returned.
If the Encryption Communication Security mode is active, then the DATA bytes are encrypted. In Authentication
Communication Security mode the DATA bytes are not encrypted.
