4.1 Control/Sense Commands
The "Transfer Byte Length" field in the CDB specifies the total number of bytes of
MODE SENSE data which can be transferred to the INIT by this command. The
HDD transfers the number of bytes of all the MODE SENSE data specified in the
"Page code" field or the portion of MODE SENSE data with the length specified
in the "Transfer Byte Length" field, whichever is smaller. When zero is specified
in the "Transfer Byte Length" field, this command is terminated without anything
being transferred.
Table 4.17 lists the data configuration in the parameter list (MODE SENSE data)
transferred to the INIT by this command. The parameter list consists of a 4-byte
header, an 8-byte block descriptor and one or more page descriptors, specified in
the CDB, which are transferred in order. However, when "1" is specified in the
DBD bit of the CDB, the block descriptor is not transferred. Also, when X'00' is
specified in the "Page code" field of the CDB, the page descriptor is not
transferred.
