Cortex-M3 Processor Registers
2.7.4.28 VTOR Register (Offset = D08h) [reset = 0h]
VTOR is shown in
Vector Table Offset
This register is used to relocated the vector table base address. The vector table base offset determines
the offset from the bottom of the memory map. The two most significant bits and the seven least
significant bits of the vector table base offset must be 0. The portion of vector table base offset that is
allowed to change is TBLOFF.
