ABSTRACT:
A peripheral controller is described which is suitable for connecting a selected one of a plurality of peripheral devices to a computer system. The peripheral controller comprises programmable bidirectional line driver/receiver devices which can be operated in an input only mode, an output only mode or a bidirectional mode and which can be set into an appropriate mode by configuration control data sent from the computer system to the peripheral controller. The peripheral controller also includes a re-configurable logic array which can be configured under the control of the configuration control data to implement a particular interface required for the selected peripheral device. This increases the efficiency of use of a peripheral interface.
