Exception priorities

Figure 13-3. 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, see

If software does not configure any priorities, then all exceptions with a configurable priority have

a priority of 0. For information about configuring exception priorities see

• a lower priority value indicating a higher priority

• configurable priorities for all exceptions except Reset, Hard fault.
