Each mode page contains a page code, a page code length, and a set of mode parameters.

PS(parameters savable):

0b(not saved)

When using the MODE SENSE command, a parameters savable (PS) bit of one indicates that the mode page can be saved by the target in non-volatile, vendor-specific location. A PS bit of zero indicates that the supported parameters cannot be saved. When using the MODE SELECT command, the PS bit is reserved. This scanner does not have page save function.
