Abstract
La presente descrizione comprende una discussione di un sistema di trasferimento di dati. Il sistema di trasferimento di dati è responsabile del trasferimento di dati verso e da un ricetrasmettitore radio (107) e da tutti i corrispondenti dispositivi periferici (111, 113) contenuti nel radiotelefono (103). Il sistema di trasferimento di dati comprende un bus di dati (109), un modulo di controllo principale nel ricetrasmettitore (107) ed un modulo di controllo periferico in ciascuno dei dispositivi periferici. Il sistema di trasferimento di dati presenta uno stato di inizializzazione ed uno stato operativo. Durante lo stato di inizializzazione, il bus di dati (109) opera ad una frequenza inferiore in confronto con lo stato operativo. La più bassa velocità aumenta il tempo concesso per l'assegnazione degli indirizzi univoci per ciascuno dei moduli di controllo periferici. Dopo la rivelazione del completamento dello stato di inizializzazione, il modulo di controllo principale conduce la commutazione allo stato operativo.
