8.10.3 Command functionality
8.10.3.1
Idle command
Command (00h);
This command indicates that the CLRC663 is in idle mode. This command is also used to
terminate the actual command.
8.10.3.2
LPCD command
Command (01h);
This command performs a low-power card detection and or an automatic trimming of the
LPO. The values of the sampled I and Q channel are stored in the register map. The value
is compared with the min/max values in the register. If it exceeds the limits, an LPCD_Irq
will be raised. After the command the standby is activated if selected.
8.10.3.3
Load key command
Command (02h), Parameter1 (key byte1),..., Parameter6 (key byte6);
Loads a MIFARE Key (6 bytes) for Authentication from the FIFO into the crypto unit.
Abort condition: Less than 6 bytes written to the FIFO.
8.10.3.4
MFAuthent command
Command (03h), Parameter1 (Authentication command code 60h or 61h), Parameter2
(block address), Parameter3 (card serial number byte0), Parameter4 (card serial number
byte1), Parameter5 (card serial number byte2), Parameter6 (card serial number byte3);
This command handles the MIFARE authentication in Reader/Writer mode to enable a
secure communication to any MIFARE classic card.
When the MFAuthent command is active, any FIFO access is blocked. Anyhow if there is
an access to the FIFO, the bit WrErr in the Error register is set.
This command terminates automatically when the MIFARE card is authenticated and the
bit MFCrypto1On is set to logic 1.
LoadReg
0Ch
(EEPROM ddressL), (EEPROM
addressH), RegAdr, (number of
Register to be copied);
reads data from the internal EEPROM and initializes the
CLRC663 registers. EEPROM address needs to be
within EEPROM sector 2
LoadProtocol
0Dh
(Protocol umber RX), (Protocol number
TX);
reads data from the internal EEPROM and initializes the
CLRC663 registers needed for a Protocol change
LoadKeyE2
0Eh
KeyNr;
copies a key of the EEPROM into the key buffer
StoreKeyE2
0Fh
KeyNr, byte1,byte2, byte3, byte4,
byte5,byte6;
stores a MIFARE key (size of 6 bytes) into the EEPROM
ReadRNR
1Ch
-
Copies bytes from the Random Number generator into
the FIFO until the FiFo is full
Soft Reset
1Fh
-
resets the CLRC663
