PC Card Enable - Read/Write
Writing a “1” to this bit enables the PC Card interface.
PC Card Reset - Read/Write
Writing a ‘1’ to this bit clears the Configuration Option
register in the card. This places the card into an
unconfigured (memory only interface) state.
Writing a ‘0’ to this bit allows normal PC Card operation.
External Wait Enable - Read/Write
Writing a ‘1’ to this bit enables the MCWAIT input pin to be
asserted by the card to insert wait cycles into the access
timing.
Writing a ‘0’ to this bit disables the MCWAIT input pin from
being asserted by the card.
