0: The BOD18 hysteresis is disabled.
1: The BOD18 hysteresis is enabled.
This controls the voltage trigger level for the BOD18.
When the flash fuse calibration is done (SCIF.BOD.FCD is set):
Refer to
These are Flash controller fuses and are described in the FLASHC section.
Default Fuse Value
SCIF.BOD.LEVEL is loaded to 0x28 if the BODLEVEL fuses are greater than 0xA.
SCIF.BOD.LEVEL is loaded to (BODLEVEL x 4) if the BODLEVEL fuses are lower or equal to 0xA.
See ”Electrical Characteristics” on page 1246.
The devices are shipped with the FGPFRLO register value: 0xF877FFFF:
See also the AT32UC3C Bootloader user guide document.
