1 INTRODUCTION
CCR612 is a computer controlled high-end AM/FM car radio system with R(B)DS (Radio Broadcasting
Data System), EON (Enhanced Other Network information) and I
2
C-bus controlled radio IC’s. CCR612S
is the controlling microprocessor. CD-changer control is also preformed by the CCR612S. It is based on
the 8051 family microcontroller P83CE528 and takes care of all radio control functions as well as R(B)DS
and EON decoding. With the following features:
Digital PLL tuning for FM, MW, LW and SW (49m) bands, (factory options: MW, LW and SW disable).
Factory option for application in different parts of the world (e.g. USA / Europe) concerning the band
limits and tuning grid.
Manual Tuning, Search Tuning and Local/Dx handling.
Frequency Scan (Continuous Search, pausing 6 seconds on every station).
Automatic Store Tuning (AST).
Search for Traffic Programmes (TP) or specific Program Types (PTY).
