A serial/parallel interface for interfacing the serial port of a microcontroller with parallel bus devices, and a protocol for communicating with the same. The interface operates to maximize through-put with minimum handshaking. When the bus device is a nonvolatile memory containing the operating software of the microcontroller system, the interface provides for dynamic updating of the operating program. It also relieves the constraints imposed on the number of bus devices accessible to the microcontroller system because of the limited number of I/O pins available on the microcontroller.
Interface série-parallèle pour interfacer le port série d'un microcontrôleur avec des dispositifs de bus parallèle, et protocole de communication avec ces derniers. L'interface maximise le débit en réduisant au minimum le dialogue d'authentification. Lorsque le dispositif de bus est une mémoire non volatile contenant le logiciel d'exploitation du microcontrôleur, l'interface assure la mise à jour dynamique du programme d'exploitation. En outre, elle remédie aux contraintes imposées aux dispositifs de bus accessibles au microcontrôleur en raison du nombre limité de broches E/S disponibles sur le microcontrôleur.
