Low-Voltage Detect Voltage Select — This bit selects the low voltage detect (LVD) trip point setting.It also
selects the warning voltage range. See Table 5-12.
Low-Voltage Warning Voltage Select — This bit selects the low voltage warning (LVW) trip point voltage. See
Table 5-12.
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.
