6.2.8.2 Vector Table
NuMicro M051
When any interrupts is accepted, the processor will automatically fetch the starting address of the
interrupt service routine (ISR) from a vector table in memory. For ARMv6-M, the vector table base
address is fixed at 0x00000000. The vector table contains the initialization value for the stack
pointer on reset, and the entry point addresses for all exception handlers. The vector number on
previous page defines the order of entries in the vector table associated with exception handler
entry as illustrated in previous section.
