interrupt vector addresses
The interrupt vectors and the power-up starting address are located in the address range 0FFFFh−0FFE0h. The
vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence.

NOTES: 1. Multiple source flags
2. Interrupt flags are located in the module.
3. (Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot
disable it.
4. A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h−01FFh) or from
within unused address ranges (MSP430F4270, MSP430F4260: from 0300h to 0BFFh and from 01100h to 07FFFh,
MSP430F4250: from 0300h to 0BFFh and from 01100h to 0BFFFh).
