This exclusive-use device will report all the CIS chains present in a
PC Card, if a 16-bit PC Card is inserted in the slot.
Only one user at a time may access the CIS.
The CIS is presented as the relevant byte stream from the PC Card.
For CIS tuples in Attribute Memory (the default), only the even
locations are presented (the ODD locations are undefined per the
standard).
For CIS tuples in Common Memory, every byte is presented to the user.
Decoding of the CIS tuples is done via a userland program.
All tuples are presented to the user.
