Privileged software can disable the exceptions that Table 2.15 (p. 23) shows as having configurable
priority, see:
For more information about hard faults, memory management faults, bus faults, and usage faults, see
2.3.3 Exception handlers
The processor handles exceptions using:
Interrupt Service Routines
(ISRs)
Interrupts IRQ0 to IRQ(n-1) (n is given by the number of interrupts
for the device, given by Table 1.1 (p. 5) ) are the exceptions handled
by ISRs.
Fault handlers
Hard fault, memory management fault, usage fault, bus fault are fault
exceptions handled by the fault handlers.
System handlers
NMI, PendSV, SVCall SysTick, and the fault exceptions are all
system exceptions that are handled by system handlers.
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 2.2 (p. 25) 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. The parameter n denotes the number of interrupts for the device, given by
