BODLEVEL[3:0]
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.
BODEN: Brown Out Detector Enable
BODHYST: Brown Out Detector Hysteresis
0: The Brown out detector hysteresis is disabled
1: The Brown out detector hysteresis is enabled
BODLEVEL: Brown Out Detector Trigger Level
This controls the voltage trigger level for the Brown out detector. Refer to Electrical Characteris-
tics section. If the BODLEVEL is set higher than VDDCORE and enabled byt 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.
LOCK, EPFL, BOOTPROT
These are Flash controller fuses and are described in the FLASHC section.
As no external memories can be connected to AT32UC3B the EPFL bit has no effect.
