Pages Notched is a bit map of the mode page codes that indicates which pages contain parameters that may
be different for different notches. The most significant bit of this field corresponds to page code 3Fh and the
least significant bit corresponds to page code 00h. If a bit is one, then the corresponding mode page con-
tains parameters that may be different for different notches. If a bit is zero, then the corresponding mode
page contains parameters that are constant for all notches.
