Interrupt Vector Addresses
The interrupt vectors and the power-up starting address are located in the address range of 0xFFFF to 0xFFC0.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.
If the reset vector (located at address 0xFFFE) contains 0xFFFF (for example, if flash is not programmed), the
CPU goes into LPM4 immediately after power up.

A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0x0000 to 0x01FF) or
from within unused address range.

This location is used as bootstrap loader security key (BSLSKEY).
A value of 0xAA55 at this location disables the BSL completely.
A value of 0x0 disables the erasure of the flash if an invalid password is supplied.

The interrupt vectors at addresses 0xFFDC to 0xFFC0 are not used in this device and can be used for regular program code if
necessary.
