8.9.1
Flash General Purpose Fuse Register Low (FGPFRLO)
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 Characteristics” on page 791.
UPROT, SECURE, BOOTPROT, EPFL, LOCK
These are Flash Controller fuses and are described in the FLASHCDW section.
8.9.1.1
Default Fuse Value
The devices are shipped with the FGPFRLO register value:0xE07FFFFF:
BODEN fuses set to 11. BOD is disabled.
BODHYST fuse set to 1. The BOD hysteresis is enabled.
BODLEVEL fuses set to 000000. This is the minimum voltage trigger level for BOD. This level
is lower than the POR level, so when BOD is enabled, it will never trigger with this default
value.
UPROT fuse set to 1.
SECURE fuse set to 11.
BOOTPROT fuses set to 111. The bootloader protection is disabled.
EPFL fuse set to 1. External privileged fetch is not locked.
LOCK fuses set to 1111111111111111. No region locked.
After the JTAG or aWire chip erase command, the FGPFR register value is 0xFFFFFFFF.
