Hardware Conditions

It is possible to force the controller to execute the bootloader after a Reset with hard-

ware conditions.

During the first programming, the user can define a configuration on Port1 that will be

recognized by the chip as the hardware conditions during a Reset. If this condition is

met, the chip will start executing the bootloader at the end of the Reset.

See a detailed description in the applicable Document.
