System Power Management Status and Control 2 Register (SPMSC2)
Figure 5-10. System Power Management Status and Control 2 Register (SPMSC2)
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 LVWACK bit is the low-voltage warning acknowledge. Writing a 1
to LVWACK clears LVWF to 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.
Power Down Control — The write-once PDC bit controls entry into the power down (stop2 and stop1) modes.
0 Power down modes are disabled.
1 Power down modes are enabled.
Partial Power Down Control — The write-once PPDC bit controls which power down mode, stop1 or stop2, is
selected.
0 Stop1, full power down, mode enabled if PDC set.
1 Stop2, partial power down, mode enabled if PDC set.
