Table 23. Reset and Interrupt Vectors
Notes:
Table 24
BOOTRST and IVSEL settings. If the program never enables an interrupt source, the interrupt
vectors are not used, and regular program code can be placed at these locations. This is also
the case if the Reset Vector is in the Application section while the interrupt vectors are in the
Boot section or vice versa.
