Shutdown
Power up default is with all bits “0” (zero).
D0 :Shutdown : When set to 1 the G751 goes to low power shutdown mode.
D1 :Comparator / Interrupt mode : 0 is Comparator mode, 1 is Interrupt mode.
D2 :O.S. Polarity : 0 is active low, 1 is active high. O.S. is an open-drain output under all conditions.
D3-D4 :Fault Queue : Number of faults necessary to detect before setting O.S. output to avoid false tripping due
