Description
4.3.5 G2READTID: Gen2 Read TID Memory Bank
4.3.6 G2READUSER: Gen2 Read USER Memory Bank
4.3.7 G2READCNTL: Gen2 Read MaxArias Control/Status
G2READTID
Gen2 TID memory bank read command
None
tid0, tid1, tid2, tid3, Handle, CRC16
Performs a standard Gen2 read command of the entire TID memory bank. The first two TID words
of a MaxArias WM72016 tag shall be: xE201_6216. This shall indicate:
G2READUSER
Gen2 USER memory bank read command
None
data
Performs a standard Gen2 read command of the entire USER memory bank. This command
functions identically to a standard G2READ command with both the address and length parameters
set to zero. The number of data words n returned for a MaxArias tag is dependent on the USER
memory bank block size setting (set by the Control/Status register – refer to the MaxArias data sheet
for additional detail). For example, n=931 (block size = 1 word/block), n=963 (block size = 2
words/block), etc.
G2READCNTL
MaxArias Control/Status read command
None
data, Handle, CRC16
Performs a standard Gen2 read command of the MaxArias Control/Status register. The parsing of
the Control/Status data word is shown in the MaxArias datasheet. Key control register bits are high-
lighted below. Particular attention should be given to the AINC (auto-increment) control bit –
notably its effect on WM72016 addressing shifting when using unaddressed writes or block-writes.
These two types of write instructions use the address contents of the working stored address register
to write data to WM72016 memory.
1. Ramtron’s “Mask Designer Identification” = x016.
2. The encoded WM72016 part number = x216.
3. Ramtron’s serial number is encoded in tid2 and tid3.
