11. Fuses Settings
The flash block contains a number of general purpose fuses. Some of these fuses have defined
meanings outside the flash controller and are described in this section.
The general purpose fuses are erase by a JTAG chip erase.

Flash General Purpose Fuse Register (FGPFRLO)
BODEN: Brown Out Detector Enable
BODHYST: Brown Out Detector Hysteresis
BODLEVEL: Brown Out Detector Trigger Level
This controls the voltage trigger level for the Brown out detector. Refer to section
for values description. 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 level and disable the BOD.
