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

NOTES: 1. Multiple source flags
2. Interrupt flags are located in the module.
3. A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h to 01FFh).
(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot disable it.
4. Access and key violations, KEYV and ACCVIFG.
5. In SPI mode: UCB0RXIFG. In I2C mode: UCALIFG, UCNACKIFG, ICSTTIFG, UCSTPIFG.
6. In UART/SPI mode: UCB0TXIFG. In I2C mode: UCB0RXIFG, UCB0TXIFG.
