is programmed, the Reset Vector will always point to the Boot Loader Reset and the fuse can
only be changed through the serial or parallel programming interface.
Table 28-4.
Note:
The Hardware Boot Enable Fuse (HWBE) can be programmed (See
special hardware conditions under reset, the bootloader execution is forced after reset.
Table 28-5.
Note:
When the HWBE fuse is enable the ALE/HWB pin is configured as input during reset and sam-
pled during reset rising edge. When ALE/HWB pin is ‘0’ during reset rising edge, the reset vector
will be set as the Boot Loader Reset address and the Boot Loader will be executed (See Figures
28-3).
