Request Compare Mask (RQ_COMPARE_MASK[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.
