Abstract

An integrated circuit includes a combined serial data output and interrupt output terminal, a serial communication control circuit; an interrupt generation circuit, and an output circuit. The output circuit includes a serial data input, an interrupt input, and a combined serial data and interrupt output. The serial data input is coupled to a serial data output of the serial communication circuit. The interrupt input is coupled to an interrupt output of the interrupt generation circuit. The combined serial data and interrupt output is coupled to the combined serial data output and interrupt output terminal.
