Abstract:
A method of automatic baud detection with adjustment to a programmable baud rate by an asynchronous receiver/transmitter, the asynchronous receiver/transmitter including a baud divisor register for storing a baud divisor and a plurality of baud divisor replacement registers for storing a plurality of baud divisor thresholds and a plurality of baud divisor replacements, the method comprising the steps of:determining the baud divisor, comprising the step of: detecting the size of a start bit of a data stream received by the asynchronous receiver/transmitter; comparing the baud divisor to the plurality of baud divisor thresholds; and selectively setting the baud divisor to a baud divisor replacement of a baud divisor replacement register of the plurality of baud divisor replacement registers storing a baud divisor threshold based on a comparison between the baud divisor and the baud divisor threshold.
