|---|---|---|---|
| 31:24 | 0h | RO | Reserved (RSVD)
|
| 23:18 | 0h | RW | Address Mask (TRP4ADDRM) 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 traps on address ranges up to 256 bytes in size. |
