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

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.
