EE471 13-SCI-2 Serial Communication Interface (SCI) SCI is an asynchronous communication system The sender and receiver each has its independent internal baud rate generation circuitry an SCI transmitter and an SCI receiver. SCI use parity bit for error checking Parity is generated in hardware for transmitted and received data. Receiver parity errors are flagged in hardware. There is a receiver wakeup feature, an idle line detect feature, a loop-back mode, and various error detection features. Two port pins provide the external interface for the transmitted data (TXD) and the received data (RXD).

EE471 13-SCI-3 Asynchronous vs. Synchronous Asynchronous means that the sender and receiver do not have a common clock. There must be a mechanism to synchronize the sender and receiver. The synchronization mechanism for SCI is based on NRZ format (one start, eight or nine data, and one stop bit).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
