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.

Multiple source flags
Interrupt flags are located in the module.
Nonmaskable: neither the individual nor the general interrupt-enable bit will disable an interrupt event.
(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable can not disable
it.
5. Timer_B7 in MSP430x14x(1) family has 7 CCRs; Timer_B3 in MSP430x13x family has 3 CCRs. In Timer_B3 there are only interrupt
flags TBCCR0, 1, and 2 CCIFGs and the interrupt-enable bits TBCCTL0, 1, and 2 CCIEs.
6. ADC12 is not implemented on the 14x1 devices.
