This paper introduces an extended serial communication technique using 89C2051. It can provide I/O FIFO of high capacity. Data are pretreated before transmission.
The feature for I2C serial bus is introduced, and taking the serial E2PROM example, methodology and software design Of achieve I2C serial bus to utilize I/O of 8031 were given.
