11.6.2.1 Relevant LoadKey command error flags
11.6.3 Authent1 command 0Ch
11.6.4 Authent2 command 14h
The LoadKey command interprets the first twelve bytes it finds in the FIFO buffer as the
key when stored in the correct key format as described in
page
checked and, if valid, are copied into the key buffer.
The LoadKey command can only be started by the microprocessor and it automatically
stops after copying the key from the FIFO buffer to the key buffer.
All bytes requested are copied from the FIFO buffer to the key buffer. If the key format is
not correct (see
into the key buffer and the KeyErr flag is set.
Table 144. Authent1 command 0Ch
The Authent1 command is a special Transceive command; it sends six argument bytes to
the card. The card’s response is not sent to the microprocessor, it is used instead to
authenticate the card to the MFRC500 and vice versa.
The Authent1 command can be triggered only by the microprocessor. The sequence of
states for this command are the same as those for the Transceive command; see
Section 11.2.3 on page
Table 145. Authent2 command 14h
The Authent2 command is a special Transceive command. It does not need an argument
byte, however all the data needed to be sent to the card is assembled by the MFRC500.
The card response is not sent to the microprocessor but is used to authenticate the card
to the MFRC500 and vice versa.
The Authent2 command can only be started by the microprocessor. The sequence of
states for this command are the same as those for the Transceive command; see
Section 11.2.3 on page
