4.5.38 Deep-sleep mode configuration register
Table 45.
This register controls the behavior of the WatchDog (WD) oscillator and the BOD circuit
when the device enters Deep-sleep mode. In addition, the WD oscillator behavior is
influenced by the WDLOCKCLK bit in the WDMODE register
blocks are shut down in Deep-sleep mode.
This register must be written before entering Deep-sleep mode and before setting the
WDT lock bit WDLOCKCLK with one of the four values shown in
Table 46.
Table 47.
Remark: Failure to initialize and program this register correctly may result in undefined
behavior of the microcontroller. The values listed in
values allowed for PDSLEEPCFG register.
To select the appropriate power configuration for Deep-sleep mode, consider the

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 if needed for timing a wake-up event (see
