3.5.44 Deep-sleep mode configuration register
This register controls the behavior of the WatchDog (WD) oscillator and the BOD circuit
when the device enters Deep-sleep mode.
This register must be initialized at least once before entering Deep-sleep mode with
one of the four values shown in
Table 49.
Remark: Failure to initialize and program this register correctly may result in undefined
behavior of the microcontroller. The values listed in
for PDSLEEPCFG register.
To select the appropriate power configuration for Deep-sleep mode, consider the
following:
Remark: Reserved bits in this register must always be written as indicated. This register
must be initialized correctly before entering Deep-sleep mode.

BOD: Leaving the BOD circuit enabled will protect the part from a low voltage event
occurring while the part is in Deep-sleep mode. However, the BOD circuit causes an
WD oscillator: The watchdog oscillator can be left running in Deep-sleep mode to
provide a clock for the watchdog timer or a general purpose timer if they are needed
for timing a wake-up event (see

The watchdog oscillator, if running, contributes an additional current drain in
