ABxF Command 84 (84H): Fill All
DESCRIPTION
Fill all RFID tags-in-field or all tags in the same family, with a one byte
value over multiple contiguous addresses.
DISCUSSION
This command is commonly used to clear an RFID tag's memory. It writes a
one byte value repetitively across a specified range of tag addresses. All tags
present in the antenna field with the specified Family ID will be affected by
this command.
The Fill All function requires one data value byte, a starting address, and a
fill length. It will fill the tag with the data value byte, starting at the specified
start address for the specified number of consecutive bytes. The Fill Length
must be set to a non-zero value (1-48).
The timeout value is given in 1 msec increments and can have a value of
1EH to FFFEH (65,534 ms). When the Anticollision Index is not zero (mul-
tiple tag-in-field enabled), the LRP820 returns a response after the timeout
expires. If the Anticollision Index is 0, a response is returned when a suc-
cessful operation is performed on 1 tag or when the timeout has expired.
When the timeout is set to 0, the LRP820 will return a syntax error.
