Abstract
A system for enabling a PC card to appropriately function in the 16-bit and 32-bit standard PCMCIA environments. If the 16-bit standard and the 32-bit standard requires a pin to be connected in a certain manner, then the pin is connected in that manner. If the 16-bit standard requires a card detect pin to be grounded and the 32-bit standard requires that same card detect pin to be connected to a voltage sense pin, then the card detect pin and voltage sense pin are connected, and the card detect pin is connected to ground via a pull-down resistor. After initialization, the standard of the PCMCIA adapter can be detected by sensing the voltage of an open-circuited voltage sense pin.
