Word 164: CF Advanced PCMCIA I/O and Memory Timing Modes Capabilities and Settings
This word describes the capabilities and current settings for CFA defined advanced timing modes using
the Memory and PCMCIA I/O interface.
Notice: The use of PCMCIA I/O or Memory modes that are 100ns or faster impose significant
restrictions on the implementation of the host:
