| 23:18 | 00h | RW | Address[7:2] Mask (ADDRESS_7_2_MASK) A 1 in any bit position indicates that any value in the corresponding address bit in a received cycle will be treated as a match. The corresponding bit in the Address field, below, is ignored. The mask is only provided for the lower 6 bits of the DWord address, allowing for decoding blocks up to 256 bytes in size. |
