* i4b_itk_ix1.c - ITK ix1 micro passive card driver for isdn4bsd
* --------------------------------------------------------------
*
* $Id: i4b_itk_ix1.c,v 1.1.1.1 2001/01/05 12:50:16 martin Exp $
*
* last edit-date: [Fri Jan 5 12:31:50 2001]
*
* mh - created
* mh - fixed FreeBSD problems reported by Kevin Sheehan
* mh - added probe routine
*
*---------------------------------------------------------------------------
*
* The ITK ix1 micro ISDN card is an ISA card with one region
* of four io ports mapped and a fixed irq all jumpered on the card.
* Access to the board is straight forward and simmilar to
* the ELSA and DYNALINK cards. If a PCI version of this card
* exists all we need is probably a pci-bus attachment, all
* this low level routines should work imediately.
*
* To reset the card:
* - write 0x01 to ITK_CONFIG
* - wait >= 10 ms
* - write 0x00 to ITK_CONFIG
*
* To read or write data:
* - write address to ITK_ALE port
* - read data from or write data to ITK_ISAC_DATA port or ITK_HSCX_DATA port
* The two HSCX channel registers are offset by HSCXA (0x00) and HSCXB (0x40).
*
* The probe routine was derived by trial and error from a representative
* sample of two cards ;-) The standard way (checking HSCX versions)
* was extended by reading a zero from a non existant HSCX register (register
* 0xff). Reading the config register gives varying results, so this doesn't
* seem to be used as an id register (like the Teles S0/16.3).
*
* If the probe fails for your card use "options ITK_PROBE_DEBUG" to get
* additional debug output.
