Omega Engineering PCI-DAS1200 manual Inte, Eoaie, Eoacl, Intcl, Adflcl, INT1, INT0, Source

Write operations to this register allow the user to select interrupt sources, enable interrupts, and clear interrupts as well as ADC FIFO flags. The following is a description of the Interrupt/ADC FIFO Register:

INT[1:0] General Interrupt Source selection bits.

						INT1				INT0				Source
							0		0				Not Defined
							0		1			End of Channel Scan
							1		0			AD FIFO Half Full
							1		1			AD FIFO Not Empty
INTE
		Enables interrupt source selected via the INT[1:0] bits.
			1	= Selected interrupt Enabled
			0	= Selected interrupt Disabled
EOAIE		Enables End-of-Acquisition interrupt. Used during FIFO'd ADC operations to indicate that the
		desired sample size has been gathered.
			1= Enable EOA interrupt
			0	= Disable EOA interrupt
EOACL		A write-clear to reset EOA interrupt status.
			1	= Clear EOA interrupt.
			0	= No effect.
INTCL		A write-clear to reset INT[1:0] selected interrupt status.
			1	= Clear INT[1:0] interrupt
			0	= No effect.
ADFLCL		A write-clear to reset latched ADC FIFO Full status.
			1	= Clear ADC FIFO Full latch.
			0	= No Effect.
			NOTE: It is not necessary to reset any write-clear bits after they are set.

Read operations to this register allow the user to check status of the selected interrupts and ADC FIFO flags. The following is a description of Interrupt / ADC FIFO Register Read bits:

EOAI	Status bit of ADC FIFO End-of-Acquisition interrupt
	1	= Indicates an EOA interrupt has been latched.
	0	= Indicates an EOA interrupt has not occurred.
INT	Status bit of General interrupt selected via INT[1:0] bits. This bit indicates that any one of
	these interrupts has occurred.
	1	= Indicates a General interrupt has been latched.
	0	= Indicates a General interrupt has not occurred.
