3.6 Memory mapping control

The Memory Mapping Control alters the mapping of the interrupt vectors that appear
beginning at address 0x0000 0000. This allows code running in different memory spaces
to have control of the interrupts.
3.6.1 Memory Mapping control register (MEMMAP - 0xE01F C040)
Whenever an exception handling is necessary, the microcontroller will fetch an instruction
residing on the exception corresponding address as described in
