Overview
MI2CV provides interface between microprocessor that conforms Philips Protocol (April 1995 Update). operate either master slave mode. performs arbitration master mode allow operate multi-master systems. slave mode, interrupt processor when recognises 7-bit 10-bit address general call address. Access core's internal control status registers provided synchronous PVCI-compatible interface (with default acknowledge). This interface allows core readily interfaced range popular on-chip buses such AMBA buses associated with CoreConnectarchitecture. MI2CV used applications which devices. These primarily consumer telecoms market segments. also used board level communications protocol.

Operating Modes MI2CV operate four modes: Master Transmit; Master Receive; Slave Transmit; Slave Receive. MI2CV will automatically enter Slave Transmit mode receives Slave Address Read bit. will similarly enter Slave Receive mode receives either Slave Address Write bit, General Call Address. Status Information state interface time indicated status code recorded MI2CV's STAT register. There status codes corresponding different possible states MI2CV, plus further code that indicates when relevant status information available. states reported cover conditions from successful transmission errors loss arbitration. appropriate microprocessor responses reported interface condition MI2CV actions these invoke detailed MI2CV Product Specification.
