ABSTRACT:
An asynchronous serial port is provided in a microcontroller that includes an address matching function that includes character matching functions such that incoming data is compared to match registers for special framing characters. Further, however, address bits are provided within the serial data, and additional matching bits are provided for matching those address bits along with the character data within the matching registers. In this way, not only is framing data detected by the detection of special characters, but a microcontroller can determine when it is being addressed in a multidrop, address bit protocol system by matching the address bit and address data.
