TAIVx, Interrupt | Texas Instruments MSP430x1xx specs

			Timer_A Registers
CCIE	Bit 4	Capture/compare interrupt enable. This bit enables the interrupt request of
		the corresponding CCIFG flag.
		0	Interrupt disabled
		1	Interrupt enabled
CCI	Bit 3	Capture/compare input. The selected input signal can be read by this bit.
OUT	Bit 2	Output. For output mode 0, this bit directly controls the state of the output.
		0	Output low
		1	Output high
COV	Bit 1	Capture overflow. This bit indicates a capture overflow occurred. COV must
		be reset with software.
		0	No capture overflow occurred
		1	Capture overflow occurred
CCIFG	Bit 0	Capture/compare interrupt flag
		0	No interrupt pending
		1	Interrupt pending
