12.4.3.3 Exception Handlers
The processor handles exceptions using:
Interrupt Service Routines (ISRs)
Interrupts IRQ0 to IRQ46 are the exceptions handled by ISRs.
Interrupts IRQ0 to IRQ46 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.
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.
NMI, PendSV, SVCall SysTick, and the fault exceptions are all system exceptions that are handled by
system handlers.
12.4.3.4 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.
vectors, for all exception handlers.
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.
