ATA MODE OPERATION
11. ATA MODE OPERATION
The CL-PD67XX PC Card interfaces can be dynamically configured to support a PC Card–compatible
ATA disk interface (commonly known as ‘IDE’) instead of the standard PC Card interface. Disk drives that
can be made mechanically-compatible with PC 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 sup-
port the needs of the ATA disk interface.
Table 11-1
lists each interface pin and its function when a
CL-PD67XX card socket is operating in ATA mode. Refer to application note AN-PD5, Configuring
PCMCIA Sockets for ATA Drive Interface for more information.
All register functions of the CL-PD67XX are available in ATA mode, including socket power control, inter-
face signal disabling, and card window control. No memory operations are allowed in ATA mode.
