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.

5. Timer_B7 in MSP430F16x/161x family has 7 CCRs; Timer_B3 in MSP430F15x family has 3 CCRs; in Timer_B3 there are only
interrupt flags TBCCR0, 1 and 2 CCIFGs and the interrupt-enable bits TBCCR0, 1 and 2 CCIEs.
