Product data sheet COMPANY PUBLIC Rev. 3.3 — 3 April 2012 171133 57 of 132 NXP Semiconductors CLRC663 Contactless reader IC Remark: If the bit RxMultiple in the RxModeReg register is set to logic 1, the Receive command does not terminate automatically. It has to be terminated by activating any other command in the CommandReg register (see Section 9.17.6 “RxMod”). 8.10.3.7 Transmit command Command (06h); The content of the FIFO is transmitted immediately after starting the command. Before transmitting the FIFO content all relevant register have to be set to transmit data. This command terminates automatically when the FIFO gets empty. It can be terminated by any other command written to the command register. 8.10.3.8 Transceive command Command (07h); This command transmits data from the FIFO and receives data from the RF field once. The first action is transmitting and after a transmission the command is changed to receive a data stream. Each transmission process starts by writing the command into CommandReg. Remark: If the bit RxMultiple in register RxModeReg is set to logic 1, this command will never leave the receiving state, because the receiving will not be cancelled automatically. 8.10.3.9 WriteE2 command Command (08h), Parameter1 (addressL), Parameter2 (addressH), Parameter3 (data); This command writes one byte into the EEPROM. If the FIFO contains no data, the command will wait until the data is available Abort condition: insufficient parameter in FIFO; Address-parameter outside of range 8.10.3.10 WriteE2PAGE command Command (09h), Parameter1 (page address), Parameter2 (data0), Parameter3...65 [data1 ..data63]; This command writes up to 64 bytes into the EEPROM. Abort condition: Insufficient parameters in FIFO; Page address parameter outside of range. 8.10.3.11 ReadE2 command Command (0Ah), Parameter1 (addressL), Parameter2 (addressH), Parameter3 (length); Reads up to 256 bytes from the EEPROM to the FIFO. If a read operation exceeds the address 1FFFh, the read operation continues from address 0000h. Abort condition: Insufficient parameter in FIFO; Address parameter outside of range. 8.10.3.12 LoadReg command Command (0Ch), Parameter1 (EEPROM addressL),Parameter2 (EEPROM addressH), Parameter3 (RegAdr), Parameter4 (number); |
