* Niccy GO@ definitions
*
* the card uses 2 i/o addressranges each using 2 bytes
*
* addressrange 0:
* offset 0 - ISAC dataregister
* offset 1 - HSCX dataregister
* addressrange 1:
* offset 0 - ISAC addressregister
* offset 1 - HSCX addressregister
*
* to access an ISAC/HSCX register, you have to write the register
* number into the ISAC or HSCX addressregister and then read/write
* data for the ISAC/HSCX register into/from the corresponding
* dataregister.
*
* Thanks to Klaus Muehle of Dr. Neuhaus Telekommunikation for giving
* out this information!
