Notes:
1. If the requested transfer volume is not equal to the actual data volume, this scanner
informs the initiator that the requested transfer amount is abnormal. This is done
as the scanner returns the status 00001 (CHECK CONDITION) and creates the
following sense data:
f ILI = 1
f INFORMATION = requested transfer amount (TL) - actual data amount
This status is usually sent to the last READ command of the sequence.
commands other than the last READ, the GOOD status is reported.) If the data
amount requested by the last READ command agrees with the last data amount
left, the GOOD status is reported to the READ command, and the CHECK
CONDITION status is reported to the next READ command.
2. In addition to the means described above in Note 1, the initiator has another means
for ascertaining the completion of transfer of image data for one window.
Specifically, the initiator issues the REQUEST SENSE command after each
completion of the READ command, and if the sense data received in response is NO
SENSE, the initiator checks the EOM bit in the sense data:
EOM bit = 0 . . . There is scan data yet to be transferred.
EOM bit = 1 . . . All scan data has been transferred.
However, issuing the REQUEST SENSE command after each completion of the
READ command is not desirable in terms of processing efficiency.
3. Once all scan data has been transferred, the CHECK CONDITION status is always
reported to the READ command that follows. Before attempting another read, first
issue the SET WINDOW command.
4. When the CMP II option is not provided, image data for one window must be read in
one READ command. If the data transfer rate is less than 1300 KB/S, a burst
transfer error occurs. (Data overflow occurs because the scanner does not have
enough memory.)
5. Enable or disable of disconnection is decided by bit 6 of the IDENTIFY message
issued by the initiator at the READ command.
disconnection must set bit 6 of the IDENTIFY message. When the CMP II option is
not provided, the disconnection is not performed even if bit 6 of the IDENTIFY
message is set.
