Low-Voltage Warning Flag — The LVWF bit indicates the low voltage warning status.
0 Low voltage warning not present.
1 Low voltage warning is present or was present.
Low-Voltage Warning Acknowledge — The LVWF bit indicates the low voltage warning status. Writing a 1 to
LVWACK clears LVWF to a 0 if a low voltage warning is not present.
Low-Voltage Detect Voltage Select — The LVDV bit selects the LVD trip point voltage (V
