Apparatus using a binary coded decimal switch and a programmable logic array for selectively coupling terminals of a controller chip to data bus lines |
摘要 |
A network interface card for a personal computer includes a controller chip and a programmable logic array that is coupled at its output terminals to the bus pull-up resistors, or to dedicated terminals of the controller chip for establishing different configurations for the controller chip on the interface card. A rotary, ten position binary coded decimal switch is coupled across the inputs of the programmable logic array. Each position of the switch establishes a different configuration for the controller. The arrangement eliminates the need for manual switches and movable jumpers for configuring the network interface card controller chip.
