HP NuDAQ I-9111DG/HR manual Hardware Interrupt Clear Register

Page 29

	1: IRQ when FIFO is half full
ISC1:	IRQ1 signal select

0:IRQ every Timer tick

1:IRQ when ExtTrg signal changes from ‘H’ to ‘L’

FFEN: FIFO enable pin

0:FIFO Enable (Power On Default value)

1:FIFO Disable

(To reset FIFO, set FFEN sequence as 0 -> 1 -> 0)

3.11Hardware Interrupt Clear Register

Because of the PCI interrupt signal is level trigger, the interrupt clear register must be written to clear the flag after processing the interrupt request event, otherwise another interrupt request will be inserted and cause the software hangs on processing the interrupt event.

Address: BASE + 48h

Attribute: write only

Data Format:

Bit	7	6	5	4	3	2	1	0

BASE+48h	X	X	X	X	X	X	X	X

3.12A/D Mode & Interrupt Control Read Back Register

The AD mode setting and interrupt control setting can be read from this register. Refer to section 3.8 and section 3.10 for the detailed definition of each bit.

Address: BASE + 0Ah

Attribute: read only

Data Format:

Bit	7	6	5	4	3	2	1	0
