ABxF Command 4 (04H): Fill Tag
DESCRIPTION
Fill an RFID tag 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.
The fill 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. When Fill
Length is set to 0, the LRP820 will write fill data from the start address to
the end of the tag’s memory. The timeout value is given in 1 msec incre
-
ments and can have a value of 1EH to FFFEH (65,534 ms). When the time
-
out is set to 0, the LRP820 will return a syntax error.
