ABSTRACT:
An improved programmable logic device programmed to maximize pin usage, and a method of using such a programmable logic device. The programmable logic device is programmed to use a data pin as an input pin by disabling the output buffer driving that pin. Then, when it is desired to drive the data pin as an output pin, the output buffer is enabled, and the pin is driven by a signal generated by the combinatorial logic on the programmable logic device.
