Function code
Common memory transfer function
The common memory transfer to or from the card permits both 8- or 16-bit access to all of
the common memory addresses. (see
Common memory function
True IDE mode I/O function
The card can be configured in a true IDE mode of operation. It is configured in this mode
only when the –OE signal is grounded by the host during the power off to power on cycle. In
this True IDE mode the PCMCIA protocol and configuration are disabled and only I/O
operations to the task file and data register are allowed. No memory or attribute registers
are accessible to the host. The Set Feature command can be used to put the device in 8-bit
mode (see
Removing and reinserting the card while the host computer’s power is on will reconfigure the
card to PC card ATA mode.
