GLIU Register Descriptions
5.1.3.18
MSR Address
Type
Reset Value
The DA Compare Value and the DA Compare Mask enable traps on specific transactions. A hit to the DA Compare is deter-
mined by hit = (DA_IN & DA_COMP_MASK) == DA_COMP_VAL). A hit can trigger the DA_CMP error sources when they
are enabled. The value is compared only after the packet is arbitrated.

Description
Reserved. Write as read.
DA Packet Compare Value [80:45]. This field forms the upper portion of the data
value that is compared to the logical bit-wise AND of the incoming data value and the
data value compare mask in order to determine a hit. The “HI” and “LO” portions of the
incoming data, the compare value, and the compare mask, are assembled into com-
plete bit patterns before these operations occur.

Description
Reserved. Write as read.
Data Packet Compare Value [44:0]. This field is forms the lower portion of the data
COMPMASK value, that is then bit-wise logically ANDed with the incoming data value
before it is compared to the DA_COMPVAL. The “HI” and “LO” portions of the incom-
ing data, the compare value, and the compare mask, are assembled into complete bit
patterns before these operations occur.
