ABSTRACT:
A method and apparatus of bringing sampling instants of a first internal coder-decoder (14) of a first microprocessor (10) into synchronization with sampling instants of a second internal coder-decoder (20) of a second microprocessor (12). The first and second microprocessors (10 and 12) wait a predetermined time to achieve phase lock. A common interrupt is generated by the first microprocessor (10). The common interrupt is simultaneously sent to and received by the first and second microprocessors (10 and 12). The first and second internal coder-decoders (14 and 20) are forced into a known state simultaneously.
