30 Description: 32/64-Channel Isolated Digital I/O Boards
31 Devices: (ADLink) PCI-7230 [adl_pci7230] - 16 input / 16 output
32 (ADLink) PCI-7233 [adl_pci7233] - 32 input
33 (ADLink) PCI-7234 [adl_pci7234] - 32 output
34 (ADLink) PCI-7432 [adl_pci7432] - 32 input / 32 output
35 (ADLink) PCI-7433 [adl_pci7433] - 64 input
36 (ADLink) PCI-7434 [adl_pci7434] - 64 output

41 The PCI-7230, PCI-7432 and PCI-7433 boards also support external
42 interrupt signals on digital input channels 0 and 1. The PCI-7233
43 has dual-interrupt sources for change-of-state (COS) on any 16
44 digital input channels of LSB and for COS on any 16 digital input
45 lines of MSB. Interrupts are not currently supported by this
48 Configuration Options: not applicable, uses comedi PCI auto config
51 #include <linux/pci.h>
53 #include "../comedidev.h"
56 * Register I/O map (32-bit access only)
