To understand how the data is interpreted, it is necessary to break down the GSE Mask
field, A4, into binary:
A4 = 1010 0100
This mask equates to the tag comparing the first, third, and sixth bytes of the
Comparison Data to data in the tag beginning at address location 0A (10 decimal).
The Comparison Data field is broken down in bytes with the bytes corresponding to the
mask underlined in bold (for clarification):
Address: 0A 0B 0C 0D 0E 0F 10 11
Data: 00 05 01 42 02 02 41 33
where
0A (10 decimal) must be equal to “00” hexadecimal, the first byte in the Comparison Data
field
0C (12 decimal) must be equal to “01” hexadecimal, the third byte in the Comparison Data
field
0F (15 decimal) must be equal to “02” hexadecimal, the sixth byte in the Comparison Data
field
