Load PC with PC relative addressing instruction:
The ARM exception vector 6 is used to store information needed by the DataFlash boot pro-
gram. This information is described below.
An example of valid vectors follows:
The size of the image to load into SRAM is contained in the location of the sixth ARM vector.
Thus the user must replace this vector by the correct vector for his application.
The DataFlash boot program performs device initialization followed by the download procedure.
