ABSTRACT:
A digital communication system including a digital controller (11), a master circuit (14) capable of communicating in a variety of serial protocols, and at least one slave circuit (16). The digital controller is preferably a microprocessor. The master circuit is configured in a selected serial protocol by the digital controller in response to data words provided by the digital controller. The slave circuit is connected to the master circuit and communicates in the master circuit's selected serial protocol under the control of data words sent from the digital controller to the master circuit. The master circuit is a bi-directional, parallel-to-serial and serial-to-parallel interface circuit having three programmable channels (CHANNEL 0, 1, 2). A method for serial communications includes coupling a master circuit (14) to a digital controller (11), coupling the master circuit to at least one slave circuit (16), and configuring the master circuit in a selected serial protocol by using a process implemented by the digital controller. The digital controller and the master circuit communicate, in parallel, by data words.
