Each of these eight descriptors checks that the physical address supplied by the device’s request on the address bits is
equal to the IBASE_SC field of descriptor register bits and that the enable write or read conditions given by the descriptor
register fields WEN and REN respectively matches the request type and enable fields given on the physical address bits of
the device’s request.
If the above matches, then the descriptor has a hit condition and routes the received address to the programmed destina-
tion ID, IDID1_SC field of the descriptor register bits.

Description
Reserved. Write as read.
Physical I/O Address Base.These bits form the matching value against which the
masked value of the physical address, bits [31:12] are directly compared. If a match is
found, then a hit is declared, depending on the setting of the BIZZARO flag comparator.
Physical I/O Address Mask. These bits are used to mask address bits [31:12] for the
purposes of this hit detection.
