Command Specifications
4-36 C141-C008
Note:
If the value specified for the "buffer full ratio" or the "buffer empty ratio" is
not within double the integral boundary of the logical data block length, the
IDD rounds up the specified value to the value which is the nearest data
block boundary. Also, if zero is specified in any of these parameters, the
IDD treats that parameter as though 1 logical data block has been specified.
However, parameter values specified from the INIT in the MODE SELECT
or MODE SELECT EXTENDED command are held as is and those values
are reported in response to a MODE SENSE or MODE SENSE EXTENDED
command. (Rounding processing of the parameters is not done by the IDD.)
Also, if the specified value does not reach 1 block, it is regarded as having
specified 1 block.
c. Bus inactivity limit (not supported)
d. Disconnect time limit (not supported)
e Connect time limit (not supported)
f. Maximum burst size
This parameter specifies the maximum data that the TARG can transfer in
one Loop OPEN, and specifies the maximum data volume that can be
transferred continuously as a multiple of 512 bytes. (Valid only for WRITE
and WRITE EXT).
In the IDD, this value is unlimited. It is impossible for this parameter to be
changed by the INIT. The IDD disregards the value specified in this
parameter and operates according to the default value"0100."
g. DTDC (data transfer disconnect control)
DTDC: Controls how to perform Loop CLOSE.
00b= Perform Loop CLOSE according to the instructions of other
parameters without using DTDC.
01b= When a data transfer by the command is started, the target will never
try Loop CLOSE until transmission of all the data to be transferred by
the command is completed. The specified values in the "connect limit
time" and "bus inactivity limit" fields are ignored during the data
transfer.
The IDD disregards the value specified in this parameter and operates
according to the default “00” value.
01b= Reserved.
11b= When a data transfer by the command is started, the target will never
try Loop CLOSE until execution of the command is completed. The
specified values in the "connect limit time" and "bus inactivity limit"
fields are ignored during the data transfer.
