Exception priorities
Figure 10-3. 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
As
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.
