ISA–to–PC-Card Host Adapters

The chips provide fully buffered PC Card interfaces,
meaning that no external logic is required for buffer-
ing signals to/from the interface, and power con-
sumption can be controlled by limiting signal
transitions on the PC Card bus.
Personal computer applications typically access PC
Cards through a third-party socket/card-services
software interface. To assure full compatibility with
industry-standard socket/card-services software and
PC Card applications, the register set in the
CL-PD6710 and CL-PD6722 is a superset of the
Intel
82365SL register set.
