Fuses Settings
0: The BOD hysteresis is disabled
1: The BOD hysteresis is enabled
This controls the voltage trigger level for the Brown out detector. For value description refer to Electrical Characteristics chapter.
If the BODLEVEL is set higher than VDDCORE and enabled by fuses, the part will be in constant reset. To recover from this
situation, apply an external voltage on VDDCORE that is higher than the BOD Trigger level and disable the BOD.
These are Flash controller fuses and are described in the FLASHC chapter.

BODLEVEL[3:0]
The flash block contains 32 general purpose fuses. These 32 fuses can be found in the Flash
General Purpose Fuse Register Low (FGPFRLO) of the Flash Controller (FLASHC).
Some of the FGPFRLO fuses have defined meanings outside the FLASHC and are described in
this section.
The general purpose fuses are set by a JTAG chip erase.
The devices are shipped with the FGPFRLO register value: 0xFFF7FFFF:
