5.8.8
This register is used to report the status of the low-voltage warning function, and to configure the stop
mode behavior of the MCU. This register should be written during the user’s reset initialization program
to set the desired controls even if the desired settings are the same as the reset settings.

System Power Management Status and Control 2 Register
(SPMSC2)
Figure 5-10. System Power Management Status and Control 2 Register (SPMSC2)
Low-Voltage Detect Voltage Select — This write-once bit selects the low-voltage detect (LVD) trip point setting.
It also selects the warning voltage range. See
Low-Voltage Warning Voltage Select — This bit selects the low-voltage warning (LVW) trip point voltage. See
Table
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 bit.
Partial Power Down Control — This write-once bit controls whether stop2 or stop3 mode is selected.
0 Stop3 mode enabled.
1 Stop2, partial power down, mode enabled.
