Abstract

L'invention concerne un procédé d'initialisation de registres d'organes périphériques d'un microcontrôleur, comprenant des étapes consistant à : accéder à des données d'initialisation dans une mémoire non volatile (NVM) reliée par un bus principal (ADB) à une unité de traitement (PU) du microcontrôleur (MC) et aux organes périphériques (PH1-PHn), activer un organe périphérique comportant des registres à initialiser, et transférer les données lues dans les registres de l'organe périphérique activé, les accès aux données d'initialisation dans la mémoire étant effectués par un circuit d'initialisation (AINT) distinct de l'unité de traitement (PU), les données d'initialisation accédées étant transmises aux organes périphériques par un bus d'initialisation (ITP) distinct du bus principal.
