UART-TYPE ASYNCHRONOUS RECEIVER WITH TWO OPERATING MODES

摘要

A asynchronous frame receiver includes an input for receiving asynchronous frames. The asynchronous frames include standard characters, and a header that has a data bit length greater than a data bit length of the standard characters. A break character detection unit detects the break character. A standard character processing unit for detecting the standard characters is activated by the break character detection unit based upon the break character being detected.
