MSR Address
Type
Reset Value
The RQ Compare Value and the RQ Compare Mask enable traps on specific transactions. A hit to the RQ Compare is
determined by hit = (RQ_IN & RQ_COMP_MASK) == RQ_COMP_VAL). A hit can trigger the RQ_COMP error sources
when they are enabled. The value is compared only after the packet is arbitrated.
5.1.3.17
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.
Request Packet Mask. This field is bit-wise logically ANDed with the incoming
Request Packet before it is compared to the RQ_COMPVAL.
Description
Reserved. Write as read.
Data Packet Compare Value [44:0]. This field forms the lower 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.
