4.2.3.7 DA Compare Value High (DA_COMPARE_VAL_HI[0:3]
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_COMPARE_MASK) == DA_COMPARE_VAL). A hit can trigger the DA_CMP error sources
when they are enabled. The value is compared only after the packet is arbitrated.

Bit Name Description
63:36 RSVD Reserved.
35:0 DAHI_VAL DA Packet Compare Value [80:45]. This field forms the upper portion of the data value
which 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 complete
bit patterns before these operations occur.
