External protocol hooks system and method

摘要

A method for enabling communications between a first communications unit and a second communications unit. The first communications unit has a first crystal that provides first unit timing for that unit. The second communications unit has a second crystal that provides second unit timing for the second communications unit. The method includes the steps of receiving the first unit timing by the second communications unit, detecting a transition of a cycle of the first unit timing received, generating a reset pulse upon each detection of the transition of the cycle of the first timing unit received, and initiating a start-up of a new sequence of the second unit timing upon occurrence of the reset pulse. Operation according to the method allows for a wide variety of external protocols to be used with appropriate communications results.
