4.2.3.4 Request Compare Value (RQ_COMPARE_VAL[0:3]
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_COMPARE_MASK) == RQ_COMPARE_VAL). A hit can trigger the RQ_CMP error
sources when they are enabled. The value is compared only after the packet is arbitrated.
Request Compare Value (RQ_COMPARE_VAL[0])
Request Compare Value (RQ_COMPARE_VAL[1])
Request Compare Value (RQ_COMPARE_VAL[2])
Request Compare Value (RQ_COMPARE_VAL[3])
2 HIT_ASMI Assert ASMI on Descriptor Hit. The descriptor hits are ANDed with the masks and then
all ORed together.
0: Disable.
1: Enable.
1HIT_DEC Decrement Counter on Descriptor Hit. The descriptor hits are ANDed with the masks
and then all ORed together.
