PCI-to-PC Card (PCMCIA) Controller — PD6729
Datasheet

ATA Mode Operation
The PD6729 card interfaces can be dynamically configured to support a PCMCIA-compatible ATA
disk interface (commonly known as ‘IDE’) instead of the standard PCMCIA card interface. Disk
drives that can be made mechanically-compatible with PCMCIA card dimensions can thus operate
through the socket using the ATA electrical interface.
Configuring a socket to support ATA operation changes the function of certain card socket signals
to support the needs of the ATA disk interface. Table 11 on page 91 lists each interface pin and its
function when a PD6729 card socket is operating in ATA mode.
All register functions of the PD6729 are available in ATA mode, including socket power control,
interface signal disabling, and card window control. No memory operations are allowed in NATA
mode.
