Hi,
I have a query regarding mode page transfer with MODE SENSE 10 command
with PC=01b.
As per the SPC-4 specification (Topic-6.13.3 Changeable values), device
returns a mask denoting those mode parameters that are changeable i.e.
other than changeable parameter's value shall be set to 0.
Here, my confusion is about the value of first 2 bytes of mode pages
which indicates {PS, SPF, PAGE CODE} in 1st byte and {PAGE LENGTH} in
2nd byte. Will it be driven 0 (as it can't be changed) or it's actual
value will be driven with PC=01b?
Similarly, for mode parameter header, what could be the value of {MODE
DATA LENGTH} field?
Thank you.

Warm Regards,
