4.2.6 IGNORE WIDE RESIDUE Message (23h)

The IGNORE WIDE RESIDUE message is sent by the target to the initiator to indicate
that the number of valid bytes sent during the last REQ/ACK handshake and
REQB/ACKB handshake of a DATA IN phase is less than the negotiated transfer width.
The Ignore field indicates the number of invalid data bytes transferred. This message is
sent immediately following that DATA IN phase and prior to any other messages. Figure
4-3 illustrates the data format of an IGNORE WIDE RESIDUE message. Table 4-6
describes the Ignore field bit definitions.
