3 * COMEDI driver for the ADLINK PCI-723x/743x series boards.
11 * COMEDI - Linux Control and Measurement Device Interface
17 * Description: 32/64-Channel Isolated Digital I/O Boards
18 * Devices: [ADLink] PCI-7230 (adl_pci7230), PCI-7233 (adl_pci7233),
19 * PCI-7234 (adl_pci7234), PCI-7432 (adl_pci7432), PCI-7433 (adl_pci7433),
20 * PCI-7434 (adl_pci7434)
23 * Status: works (tested on PCI-7230)
29 * PCI-7230 - 4 subdevices: 0 - 16 input, 1 - 16 output,
30 * 2 - IRQ_IDI0, 3 - IRQ_IDI1
31 * PCI-7233 - 1 subdevice: 0 - 32 input
32 * PCI-7234 - 1 subdevice: 0 - 32 output
33 * PCI-7432 - 2 subdevices: 0 - 32 input, 1 - 32 output
34 * PCI-7433 - 2 subdevices: 0 - 32 input, 1 - 32 input
35 * PCI-7434 - 2 subdevices: 0 - 32 output, 1 - 32 output
37 * The PCI-7230, PCI-7432 and PCI-7433 boards also support external
38 * interrupt signals on digital input channels 0 and 1. The PCI-7233
39 * has dual-interrupt sources for change-of-state (COS) on any 16
43 * Currently, this driver only supports interrupts for PCI-7230.
54 * Register I/O map (32-bit access only)
