AUTONOMOUS TRANSMIT ERROR DETECTION OF SERIAL COMMUNICATION LINK RECEIVER-TRANSMITTER AND MICROCONTROLLER SYSTEM PERIPHERALS IMPLEMENTING THE SAME

摘要

A serial communication link receiver-transmitter with autonomous transmission error detection is described, and a communication peripherals including the same. Transmit data at a transmitter and transmitted data output by the transmitter and received by the receiver are observed by an error detector configured to generate an error indication in response to difference between the transmit data and corresponding observed transmit data of a transmitted data frame. If a difference is detected a transmit error indicator is asserted.
