Interrupt Vector Addresses
The interrupt vectors and the power-up starting address are located in the address range 0FFFFh to 0FFC0h.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.
If the reset vector (located at address 0FFFEh) contains 0FFFFh (for example, if flash is not programmed) the
CPU goes into LPM4 immediately after power-up.

0FFC0h
(1)
A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h to 01FFh) or from
within unused address ranges.
(2)
Multiple source flags
(3)
(non)-maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
(4)
Interrupt flags are located in the module.

MSP430G2x52 only
(6)
The interrupt vectors at addresses 0FFDEh to 0FFC0h are not used in this device and can be used for regular program code if
necessary.
