Multiple protocol contactless reader IC (MIFARE/I-CODE1)
11.6 Error handling during command execution
If an error is detected during command execution, the PrimaryStatus register Err ag is
set. The microprocessor can evaluate the status ags in the ErrorFlag register to get
information about the cause of the error.
11.7 MIFARE security commands
11.7.1 LoadKeyE2 command 0Bh
The LoadKeyE2 command interprets the rst two bytes found in the FIFO buffer as the
EEPROM starting byte address. The EEPROM bytes starting from the given starting byte
address are interpreted as the key when stored in the correct key format as described in
Section 9.2.3.1 “Key format” on page 18. When both argument bytes are available in the
FIFO buffer, the command executes.
The LoadKeyE2 command can only be started by the microprocessor and it automatically
stops after copying the key from the EEPROM to the key buffer.
11.7.1.1
Relevant LoadKeyE2 command error ags
If the key format is incorrect (see Section 9.2.3.1 “Key format” on page 18) an undened
value is copied into the key buffer and the KeyErr ag is set.
11.7.2 LoadKey command 19h
