PCMCIA vs. ISA Pinout Comparison
The pins listed below are pin definition changes spe-
cific to PCMCIA mode: In PCMCIA mode, a number of
the input pins have internal resistors turned on with a
PCMCIA Pin Specification Changes
In ISA mode, the IOCHRDY and IOCS16 signals are
defined as Open Drain outputs. In PCMCIA mode,
the WAIT and I
