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 (0xFFFE) contains 0xFFFF (e.g., flash is not programmed) the CPU enters LPM4 after power-up.

NOTES: 1. A reset is executed if the CPU tries to fetch instructions from within the module register memory address range (0x0000 to 0x01FF).
2. Multiple source flags.
3. Interrupt flags are located in the module.
4. In SPI mode: UCB0RXIFG. In I2C mode: UCALIFG, UCNACKIFG, ICSTTIFG, UCSTPIFG.
5. In UART/SPI mode: UCB0TXIFG. In I2C mode: UCB0RXIFG, UCB0TXIFG.
6. (Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
7. This location is used as bootstrap loader security key (BSLSKEY).
A 0xAA55 at this location disables the BSL completely.
A zero (0h) disables the erasure of the flash if an invalid password is supplied.
8. The interrupt vectors at addresses 0xFFDC to 0xFFC0 are not used in this device and can be used for regular program code if
necessary.
