IOis8 - This bit when set, indicates to the
LAN91C94 that the host is limited to 8 bit
interface. In PCMCIA mode the LAN91C94 will
operate in 8 bit mode whenever ((IOis8= 1) +
(nEN16 = 1) . (16BIT = 0)). Otherwise the
LAN91C94 operates in 16 bit mode.
INTR - This read only bit reflects the status of
the nIREQ pin. The INTR bit is set when nIREQ
is low, and clear when nIREQ is high.
NOTE: The COR and CSR bits have no effect
on ISA mode.
