Note : The minimum time from the reception of ACK in the (N-m) -th byte to the output of REQ in the N-th byte with
Maximum offset count = m.
The following timing chart assumes that REQ output is aborted because output of REQ in the N-1-th byte
has made the number of offsets the maximum offset count = m.
The maximum offset count is set by bits 7 to 4 in the SCSI block transfer mode register.
