Mode Setting—Indicates this setting is on a mode-by-mode basis. Settings obtained
from this call are stored in Electrical Erasable Programmable Read Only Memory
(EEPROM) and restored upon mode set. They can be changed by running this
function again or by resetting Factory Presets only while in the mode you want to
restore.
