Generic I/O Decode Range 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.
