41 This driver only attaches using the PCI PnP auto config support
42 in the comedi core. The module parameter 'comedi_autoconfig'
43 must be 1 (default) to enable this feature. The COMEDI_DEVCONFIG
44 ioctl, used by the comedi_config utility, is not supported by
47 The PCI-7230, PCI-7432 and PCI-7433 boards also support external
48 interrupt signals on digital input channels 0 and 1. The PCI-7233
49 has dual-interrupt sources for change-of-state (COS) on any 16
50 digital input channels of LSB and for COS on any 16 digital input
51 lines of MSB. Interrupts are not currently supported by this
