The location of the vector table is determined by the vector base address register (VBA). The value in this register is used as
the upper 14 bits of the interrupt vector VAB[20:0]. The lower seven bits are determined based on the highest priority interrupt
and are then appended to VBA before presenting the full VAB to the core. Refer to the device’s reference manual for details.
The reset startup addresses of 56F824x and 56F825x are different.

•
The 56F825x’s startup address is located at 0x00 0000. The reset value of VBA is reset to a value of 0x0000 that
corresponds to the address 0x00 0000.
