Abstract
Data is transmitted asynchronously between a master and a slave microprocessor unit by first converting the number representing the word or part thereof to be transmitted into a time interval, transmitting a pulse having a width corresponding to the time interval and, at the receiver, reconverting the pulse width (time interval) to a number. Conversion and reconversion can be accomplished by, respectively, down counting a counter with a fixed frequency from the number constituting the word to be transmitted and up-counting a counter during the received pulse width at the same frequency.
