<p>A System for enabling a PC card (10) to approximately 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 (24) to be grounded and the 32-bit standard requires that same card detect pin (24) to be connected to a voltage sense pin (26), then the card detect pin and voltage sense pin are connected (26), and the card detect pin (24) is connected to ground via a pull-down resistor. After initialization, the standard of the PCMCIA adapter (12) can be detected by sensing the voltage of an open-circuited voltage sense pin.</p> |
