0: The register is read/write
1: The register is read-only, to protect against further accidental writes.
This bit is cleared after any reset except for a BOD reset, and during flash calibration.
0: The flash calibration will be redone after any reset.
1: The flash calibration will be redone after any reset except for a BOD reset.
This bit is cleared after any reset, except for a BOD reset.
This bit is set when the CTRL, HYST and LEVEL fields have been updated by the flash fuses after a reset.
0: No hysteresis.
1: Hysteresis on.
This field sets the triggering threshold of the BOD. See Electrical Characteristics for actual voltage levels.
Note that any change to the LEVEL field of the BOD register should be done with the BOD deactivated to avoid spurious reset
or interrupt.
BOD Control Register
Operation Mode for BOD
Description
BOD is disabled.
BOD is enabled and can reset the device. An interrupt request will be generated, if enabled in the IMR
register.
BOD is enabled but cannot reset the device. An interrupt request will be generated, if enabled in the IMR
register.
