Command Codes

Table 6-11 lists the valid commands that the MCU can send to the reader.

Table 6-11 Command Codes

COMMAND CODECOMMANDCOMMENTS
0x00 Idle
0x03 Software Initialization Same as power-on reset
0x0F Reset FIFO
0x10 Transmission Without CRC
0x11 Transmission With CRC
0x12 Delayed Transmission Without CRC
0x13 Delayed Transmission With CRC
0x14 End of Frame/Transmit Next Time Slot Used for ISO/IEC 15693 only
0x16 Block Receiver
0x17 Enable Receiver
0x18 Test Internal RF RSSI at RX input with TX off
0x19 Test External RF RSSI at RX input with TX off
0x1A Receiver Gain Adjust

The command code values from Table 6-11 are substituted in Table 6-12, Bits 0 to 4. Also, the most significant bit (MSB) in Table 6-12 must be set to 1.

Table 6-12 Address/Command Word Bit Distribution

BITDESCRIPTION BIT FUNCTIONADDRESSCOMMAND
B7 Command control bit 0 = Address
1 = Command
0 1
B6 Read/Write 0 = Write
1 = Read
R/W 0
B5 Continuous address mode Continuous mode Not used
B4 Address/Command bit 4 Adr 4 Cmd 4
B3 Address/Command bit 3 Adr 3 Cmd 3
B2 Address/Command bit 2 Adr 2 Cmd 2
B1 Address/Command bit 1 Adr 1 Cmd 1
B0 Address/Command bit 0 Adr 0 Cmd 0

The MSB determines if the word is to be used as a command or address. The last two columns of Table 6-12 show the function of separate bits depending on whether address or command is written. Command mode is used to enter a command resulting in reader action (for example, initialize transmission, enable reader, or turn the reader on or off).
