2 0 Introduction Both and Compact Flash standards define a mode in which the card can operate as though it is a hard disk drive. This is called mode operation. For this mode, the pins of the card interface are redefined to match the signal usage in the ATA Specification. The following sections of this white paper show the modified pin mappings and example schematics of adapter circuits for both s and CF Cards. 0 for s The following table shows the pin mapping for s in various modes.

The next page shows a sample schematic of how to connect the pins from a socket to the 0 pin ATA connector on a typical host motherboard so that the can be use in mode.
