11.4.11 WRITE_MULTIPLE

This command is used to write to and to verify multiple tags in parallel.

When receiving the WRITE_MULTIPLE command, a tag which is in the ID state or the

DATA_EXCHANGE state reads the lock information for the byte on the specified memory

content beginning at the specified ADDRESS. In case the memory is locked, it does

nothing. In case unlocked, it programs the BYTE_DATA into the specified memory.

In case the write access was successful, the tag sets the WRITE_OK bit. Otherwise, it

resets it.

The tag will not send any response.

Remark: As there is not tag response following this command, the 1 x STDEL has to be

used

11.4.12 WRITE4BYTE_MULTIPLE

This command is used to write to and to verify multiple tags in parallel.

When receiving the WRITE4BYTE_MULTIPLE command, a tag which is in the ID state or

the DATA_EXCHANGE state reads the lock information for the byte on the specified

memory content beginning at the specified ADDRESS. In case the memory is locked, it

does nothing. In case unlocked, it programs the BYTE_DATA into the specified memory.

Executing WRITE4BYTE_MULTIPLE a tag only writes those bytes that are selected by

the BYTE_MASK.

In case the write access was successful, the tag sets the WRITE_OK bit. Otherwise, it

resets it.

The starting address for the WRITE4BYTE_MULTIPLE command must be on a 4-byte

page boundary.

The tag will not send any response.

BYTE_MASK of the command:

ADDRESS

bit of BYTE_MASK to select whether byte should be written

[ADDRESS+0]

[ADDRESS+1]

[ADDRESS+2]

[ADDRESS+3]

Remark: As there is not tag response following this command, the 1 x STDEL has to be

used
