3.3.10 Mode Sense
The MODE SENSE (6) command provides a means for a target to report
parameters to the initiator. It is a complementary command to the MODE
SELECT (6) command.
Mode Sense CDB
A disable block descriptors (DBD) bit of zero indicates that the target may return
zero or more block descriptors in the returned MODE SENSE data, at the
target’s discretion. A DBD bit of one specifies that the target shall not return any
block descriptors in the returned MODE SENSE data. The page control (PC)
field defines the type of mode parameter values to be returned in the mode
pages. The page code specifies which mode page to return.
3.3.11 Send Diagnostics – 1Dh
The SEND DIAGNOSTIC command requests that the SC35 perform diagnostic
operations on itself. The only mandatory implementation of this command is the
self-test feature with the parameter list length of zero.
