Bits 11:8 – HYST[3:0] BOD33 Hysteresis Voltage Value on V
DD
This field sets the hysteresis voltage value related to "BOD33 Threshold Level on VDD" field when the
BOD33 monitors VDD.
These bits are loaded from NVM User Row at start-up.
This field is not synchronized.
Value Description
0
No hysteresis.
N
Hysteresis value is set to N*HYST_STEP.
See the Electrical Characteristics section for the HYST_STEP voltage level.
Bit 7 – RUNBKUP BOD33 Configuration in Backup Sleep Mode
This field is not synchronized.
Value Description
0
In backup sleep mode, the BOD33 is disabled.
1
In backup sleep mode, the BOD33 is enabled and configured in sampling mode.
Bit 6 – RUNHIB BOD33 Configuration in Hibernate Sleep Mode
This field is not synchronized.
Value Description
0
In hibernate sleep mode, the BOD33 is disabled.
1
In hibernate sleep mode, the BOD33 is enabled and configured in sampling mode.
Bit 5 – RUNSTDBY Run in Standby
This bit is not synchronized.
Value Description
0
In standby sleep mode, the BOD33 is disabled.
1
In standby sleep mode, the BOD33 is enabled.
Bit 4 – STDBYCFG BOD33 Configuration in Standby Sleep Mode
If the RUNSTDBY bit is set to '1', the STDBYCFG bit sets the BOD33 configuration in standby sleep
mode.
This field is not synchronized.
Value Description
0
In standby sleep mode, the BOD33 is enabled and configured in normal mode.
1
In standby sleep mode, the BOD33 is enabled and configured in low power mode.
Bits 3:2 – ACTION[1:0] BOD33 Action
These bits are used to select the BOD33 action when the supply voltage crosses below the BOD33
threshold.
