ABSTRACT:
The present invention is directed to an onboard multiprotocol communications controller global serial channel ("GSC"). The GSC as disclosed and claimed herein is for use with an 8-bit microcontroller for intelligent communications with peripheral systems or components. The microcontroller and GSC are implemented on a single integrated circuit chip. The microcontroller is a derivative of the 8051 series of microcontrollers sold by INTEL Corporation. The invented GSC interface supports synchronous data link control (SDLC), carrier-sense multi-access with collision detection (CSMA/CD), and user definable (non-standard) protocols. The flexibility in defining non-standard protocols provides the ability to retrofit new products into older serial technologies, as well as the development of proprietary interconnect schemes for serial backplane environments. The GSC operates in full duplex or half-duplex mode and performs cyclic redundancy checking (CRC) for 16 or 32 bits. Data encoding is in Manchester, NRZI or NRZ formats. The GSC may be accessed directly by the processor of the microcontroller or through a direct memory access (DMA) channel.
