MFRC630

Contactless reader IC

Reads out the EEPROM and copies the values to the RX-Protected area and to the TX-

protected area. These are all important registers to a Protocol selection.

Abort condition: Insufficient parameter in FIFO

8.10.3.13

LoadKeyE2 command

Command (0Eh), Parameter1 (key number);

Loads a MIFARE key for authentication from the EEPROM into the crypto 1 unit.

Abort condition: Insufficient parameter in FIFO; KeyNr is outside the MKA.

8.10.3.14

StoreKeyE2 command

Command (0Fh), Parameter1 (KeyNr), Parameter2(keybyte1), Parameter3(keybyte2),

Parameter4(keybyte3), Parameter5(keybyte4), Parameter6(keybyte5), Parameter7

(keybyte6);

Stores MIFARE Keys into the EEPROM. The key number parameter indicates the first key

(n) in the MKA that will be written. If more than one MIFARE Key is available in the FIFO

then the next key (n+1) will be written until the FIFO is empty. If an incomplete key (less

than 6 bytes) is written into the FIFO, this key will be ignored and will remain in the FIFO.

Abort condition: Insufficient parameter in FIFO; KeyNr is outside the MKA;

8.10.3.15

GetRNR command

Command (1Ch);

This command is reading Random Numbers from the random number generator of the

MFRC630. The Random Numbers are copied to the FIFO until the FIFO is full.
