System Power Management Status and Control 2 Register
(SPMSC2)
Figure 5-11. System Power Management Status and Control 2 Register (SPMSC2)
Power Down Flag — This read-only status bit indicates the MCU has recovered from stop1 mode.
0 MCU has not recovered from stop1 mode.
1 MCU recovered from stop1 mode.
Partial Power Down Flag — This read-only status bit indicates that the MCU has recovered from stop2 mode.
0 MCU has not recovered from stop2 mode.
1 MCU recovered from stop2 mode.
Partial Power Down Acknowledge — Writing a 1 to PPDACK clears the PPDF and the PDF bits.
Power Down Control — The 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 PPDC bit controls which power down mode is selected.
0 Stop1 full power down mode enabled if PDC set.
1 Stop2 partial power down mode enabled if PDC set.
