2.3.4 Vector table
The vector table contains the reset value of the stack pointer, and the start addresses, also
called exception vectors, for all exception handlers. Figure 11 on page 40 shows the order
of the exception vectors in the vector table. The least-significant bit of each vector must be
1, indicating that the exception handler is Thumb code.
Figure 11. Vector table
On system reset, the vector table is fixed at address 0x00000000. Privileged software can
write to the VTOR to relocate the vector table start address to a different memory location, in
the range 0x00000080 to 0x3FFFFF80. For further information see Vector table offset
register (VTOR) on page 227.
