| Description | Remap This register provides the remap base address location where a matched addresses are remapped. The three most significant bits and the five least significant bits of the remap base address are hard-coded to 3'b001 and 5'b00000 respectively. The remap base address must be in system space and is it required to be 8-word aligned, with one word allocated to each of the eight FPB comparators. |
