CL-PD6833
PCI-to-CardBus Host Adapter
14. ATA MODE OPERATION
The CL-PD6833 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 14-1 lists each interface pin and its function when a
CL-PD6833 card socket is operating in ATA mode. Refer to the Cirrus Logic application note Configuring
PCMCIA Sockets for ATA Drive Interface (AN-PD5) for more information.
All register functions of the CL-PD6833 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.
NOTE: General Windows 5 and 6 must be used for proper ATA operation.
