Function and Explanation
MODE (Data Mode Configuration: selects a mode)
Selects the data pump operation mode. All modes unlisted below
should be considered Reserved. The host should read MODE, one
time after writing it, to allow the data pump enough time to begin
operation in the new mode. Setting MODE to 0 (STANDBY) starts
the IDLE mode of operation, not the power-saving SLEEP mode.
