data from the start address to the end of the tag's memory. The
timeout value is given in 1 msec increments and can have a value of
1EH to FFFEH (65,534 ms). When the timeout is set to 0, the LRP75
will return a syntax error.
EXAMPLE
Writes 'A' (41H) to the tag starting at address 0005H for the following
next consecutive 10 bytes. A timeout of 2 seconds (07D0H = 2000 x 1
msec increments) is set for the completion of the configuration.
