Appendix D: Deprecated and Modified Commands 237

For more information about the MemBank structure and the memory map of the Gen2

tag, please refer to the EPC Global GEN2 protocol specification. This command is not

supported by the EPC1 protocol.

Lock Tag (25h)

The Lock Tag command locks a specific address in the tag data section. The ID of the

tag, the address to lock, and a password for killing the tag need to be provided.

For the GEN2 protocol, the command format is as follows.

The Lock command sends a command sequence including Lock described in the Gen2

specification. The 32-bit Access Password argument must contain the access password

that was written previously to word addresses 0x02 and 0x03 (bit addresses 0x20-0x3F)

of the tag.

The Mask and Action bits correspond to the identically named fields described in Section

6.3.2.10.3.5 of the Gen2 specification. Each of these 10-bit fields is right-aligned (LSB-

aligned) in the corresponding 16-bit argument to the serial command, as shown in the

following table. These fields are passed directly to the tag.
