PRELIMINARY DATA SHEET

Micronas

D1:7ef

R/W

Service Component Selection (0..7) and Decoding Control

bit [15]

OutputMute

normal operation

mute output

bit [14]

AutoScan Autoscan function

disable autoscan function

enable autoscan function,

skip non-audio SCs

bit [13]

BCChange Broadcast Channel Change

cleared on SCH-rescynchronization

clears all previous SCH-information

Setting this bit clears all previous SCH-information and thus pre-

pares the MAS 3506D for a BC-change. This ensured the availabil-

ity of the correct SCH-data for the new BC.

bit [12]

MPEGResync

allows resynchronization only after

SCH-detection

MPEG-resynchronization enabled

bit [11:3]

reserved, set to 0

bit [2:0]

Zero-based number of audio Service

Component to be decoded

decode SC 1

...

decode SC 8

NumSC

D1:7f0

R/W

Counter for Broadcast Channel Frames

bit [15:0]

BCCount

Counter for the decoded Broadcast

Channel frames

The BCFrameCnt ist incremented by one for each successfully

decoded BC-frame (432 ms) since reset. This address is writable,

thus the controller may reset/preset the content at any time to an

arbitrary value.

R/W

Counter for MPEG Frames

bit [15:0]

MPEGFrameCnt

Counter for the decoded MPEG-frames

The MPEGFrameCnt ist incremented by one for each successfully

decoded MPEG-frame (24...72 ms) since reset. This address is

writable for a reset/preset.
