34 * One or two subdevices are setup by this driver depending on
35 * the number of digital inputs and/or outputs provided by the
36 * board. Each subdevice has a maximum of 32 channels.
38 * PCI-7230 - 2 subdevices: 0 - 16 input, 1 - 16 output
39 * PCI-7233 - 1 subdevice: 0 - 32 input
40 * PCI-7234 - 1 subdevice: 0 - 32 output
41 * PCI-7432 - 2 subdevices: 0 - 32 input, 1 - 32 output
42 * PCI-7433 - 2 subdevices: 0 - 32 input, 1 - 32 input
43 * PCI-7434 - 2 subdevices: 0 - 32 output, 1 - 32 output
45 * The PCI-7230, PCI-7432 and PCI-7433 boards also support external
46 * interrupt signals on digital input channels 0 and 1. The PCI-7233
47 * has dual-interrupt sources for change-of-state (COS) on any 16
48 * digital input channels of LSB and for COS on any 16 digital input
49 * lines of MSB. Interrupts are not currently supported by this
52 * Configuration Options: not applicable, uses comedi PCI auto config
55 #include <linux/module.h>
57 #include "../comedi_pci.h"
60 * Register I/O map (32-bit access only)
