6.4.1 ABxS Command 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 contiguous segments of a 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 fills 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 controller writes fill data from the start address to the end of the tag's memory. The timeout value is given in 1 ms increments and can have a value of 001EH to FFFEH (65,534 ms). When the timeout is set to 0, the controller returns a syntax error.

Field	Remarks
Command	Command number in hex preceded by AAH

Start Address	Tag address where the fill starts

Fill Length	Number of tag addresses to be filled in bytes

Timeout	Timeout value given in 1 ms units (1EH - FFFEH)

Data Value Byte	Byte to be used as fill

Message Terminator	FFFFH

Example

The goal is to write ASCII 'A' (41H) to the ten bytes of tag memory starting at byte address 5. A timeout of 2 seconds (07D0H = 2000 x 1 ms increments) is set for the completion of the command.
