Write operations to this register allow the user to select interrupt sources, enable interrupts, 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.

AD FIFO Not Empty11

AD FIFO Half Full01

End of Channel Scan10

External 00

SourceINT0 INT1

INTE

Enables interrupt source selected via the INT[1:0] bits.

1 = Selected interrupt Enabled

0 = Selected interrupt Disabled

DAHFIE

Enables DAC FIFO Half-Full signal as interrupt source. Used for high speed DAC

operations.

1= Enable DAC FIFO Half-Full interrupt

0 = Disable DAC FIFO Half-Full interrupt

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

AHFCL

A write-clear to reset DAC FIFO Half-Full interrupt status.

1 = Clear DAC FIFO Half-Full interrupt.

0 = No effect.

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.

DAEMIE

Enables DAC FIFO Empty signal as an interrupt source.

1 = Enables DAC FIFO Empty interrupt.

0 = Disables DAC FIFO Empty interrupt.

ADFLCL

A write-clear to reset latched ADC FIFO Full status.

Clear ADC FIFO Full latch.

0 = No Effect.
