The MaxArias blockwrite instruction allows multiple data words (up to 127) to be written to the USER memory bank
with a single instruction. The MaxArias block-write instructions defined here are designed to support the block-write
syntax specifically for MaxArias tags.

Description
4.4.10 G2BLKWRITE: Gen2 MaxArias Blockwrite Command
G2BLKWRITE {addr} {data0} {data1} {…} {data_n-2} {data_n-1}
Gen2 MaxArias n-word blockwrite
None
Performs a MaxArias Gen2 blockwrite command with a 1 to 127 data word payload. A MaxArias
blockwrite command shall write data to the memory address pointer defined by the Working Stored
Address register (refer to the MaxArias data specifically regarding the affect of the auto-increment
bit on the blockwrite starting address using the Working Stored Address). The CLI G2BLKWRITE
command provides a convenient method with a single command to write multiple data words without
the requirement of manually updating the Working Stored Address register.
NOTE: When using the G2BLKWRITE command to write to the WM72016, an address shift of the
data will occur if the tag’s AUTOINCR bit in the CNTL/STAT register is set. To avoid the shift, do
one of the following:
Parameter
addr
data
1. Clear the tag’s AUTOINCR control bit, or
2. Account for the address shift in the G2BLKWRITE ‘addr’ parameter by subtracting 1.
Value (hex)
5-3E7
user-defined Up to 127 data words may be defined, with a space delimiting each
Definition
The maximum address is defined by the USER memory bank block
size (the maximum address defined is given for a block size = 128
words/block).
