Dedicated DDC integrable multimode communications cell

摘要

A cell of an integrated circuit dedicated to a microprocessor, the cell comprising a data input/output circuit connected to a communications network working according to at least two different protocols called the DDC1 and I2C protocols and a control circuit provided with a sequencer, the control circuit being managed by the sequencer, the control circuit communicating with a control bus of the microprocessor and with the data input/output circuit; wherein the cell comprises a logic circuit which enforces the state of the sequencer as a function of an information element which identifies which of said protocols is being used.
