Per Target - Synch Offset
This value is negotiated between initiator and target when the target is able to
operate in synchronous mode. The common value is agreed upon via Messages
between initiator and target. The Synch Offset is the maximum number of REQ
pulses allowed to be outstanding before the corresponding ACK pulses are
received. This value is usually a function of the buffering available on the
device.
Per Target - Width
This value reports the result of negotiations between initiator and target for
whether the target will operate in wide mode. A value of 0 for this field indicates
the target width is 8 bits. A value of 1 indicates 16 bit mode operation.
Per Target - Selected Sense Bytes
If the Selected Sense option is in effect, these 16 fields indicate which Sense
bytes, in which order, will be returned from the device.
If you have enabled 16 Selected Sense Bytes using the Extended Unit Options
command you will receive the Selected Sense bytes in two Status Blocks. In
that case, the first eight Sense byte Fields displayed in the Board Information
Data Structure will be returned with the first Status Block. The last eight will
appear in the second Status Block.
