Low-Voltage Warning Flag — The LVWF bit indicates the low voltage warning status.
0 Low voltage warning not preset.
1 Low voltage warning is present or was present.
Low-Voltage Warning Acknowledge — The LVWACK bit is the low-voltage warning acknowledge.
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
0 Low trip point selected (V
1 High trip point selected (V
Low-Voltage Warning Voltage Select — The LVWV bit selects the LVW trip point voltage (V
0 Low trip point selected (V
1 High trip point selected (V
Partial Power Down Flag — The PPDF bit indicates that the MCU has exited the stop2 mode.
0 Not stop2 mode recovery.
1 Stop2 mode recovery.
Partial Power Down Acknowledge — Writing a 1 to PPDACK clears the PPDF bit.
Partial Power Down Control — The write-once PPDC bit controls whether stop2 or stop3 mode is selected.
0 Stop3 mode enabled.
1 Stop2, partial power down, mode enabled.
