Vector Table
There are two types of vector table: fixed and relocatable. Each vector in the vector table consists of 4 bytes and specifies
the address where the corresponding exception handling routine starts.
2.6.1
Fixed Vector Table
The fixed vector table is allocated to a fixed address range. The individual vectors for the privileged instruction
exception, undefined instruction exception, floating-point exception, non-maskable interrupt, and reset are allocated to
addresses in the range from FFFFFF80h to FFFFFFFFh.
