This function returns a PC Card and socket to a simple memory only interface and sets the card to configuration zero by writing a 0 to the PC card's COR (Configuration Option Register).
Card Services may remove power from the socket if no clients have indicated their usage of the socket by an active csx_RequestConfiguration(9F) or csx_RequestWindow(9F).
Card Services is prohibited from resetting the PC Card and is not required to cycle power through zero (0) volts.
After calling csx_ReleaseConfiguration() any resources requested via the request functions csx_RequestIO(9F), csx_RequestIRQ(9F), or csx_RequestWindow(9F) that are no longer needed should be returned to Card Services via the corresponding csx_ReleaseIO(9F), csx_ReleaseIRQ(9F), or csx_ReleaseWindow(9F) functions. csx_ReleaseConfiguration() must be called to release the current card and socket configuration before releasing any resources requested by the driver via the request functions named above.
