MFRC630

Contactless reader IC

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.

8.10.3.7

Transceive command

Command (07h);

This command transmits data from the FIFO and receives data from the RF field at 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.

8.10.3.8

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.

8.10.3.9

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.

8.10.3.10

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.

8.10.3.11

LoadReg command

Command (0Ch), Parameter1 (EEPROM addressL),Parameter2 (EEPROM addressH),

Parameter3 (RegAdr), Parameter4 (number);

Read a defined number of bytes from the EEPROM and copies the value into the Register

set, beginning at the given address RegAdr.

Abort condition: Insufficient parameter in FIFO; Address parameter outside of range.

8.10.3.12

LoadProtocol command

Command (0Dh), Parameter1 (Protocol number RX), Parameter2 (Protocol number TX);
