25.3.3.5 Exception priorities
The vector table is fixed at address 0x00000000.
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
Configurable priority values are in the range 0-192, in steps of 64. The Reset, HardFault,
and NMI exceptions, with fixed negative priority values, always have higher priority than
any other exception.
