GLIU Register Descriptions (Continued)

5.1.3.18

Data Compare Value High (GLIU_DA_COMP_VAL_HI)

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.

5.1.3.19

Data Compare Mask Low (GLIU_DA_COMP_MASK_LO)

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_COMP error sources when they

are enabled. The value is compared only after the packet is arbitrated.

COMPVAL

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.

DALO_COMPMASK

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.
