Product data sheet COMPANY PUBLIC Rev. 3.3 — 3 April 2012 171133 55 of 132 NXP Semiconductors CLRC663 Contactless reader IC 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 Table 43.
