6.4. Manual/Compatibility Mode:
Description of Demodulator Read Registers
Note:
The use of these register is no longer recom-
mended. It should be used only in cases where soft-
ware compatibility to the MSP 34x5D is required.
Using the STANDARD SELECTION register together
with the STATUS register provides a more economic
way to program the MSP 34x5G and to retrieve infor-
mation from the IC.
All registers except C_AD_BITs are 8 bit wide. They
can be read out of the RAM of the MSP 34x5G if the
MSP 34x5D compatibility mode is required.
All transmissions take place in 16-bit words. The valid
8-bit data are the 8 LSBs of the received data word.
If the Automatic Sound Select feature is not used, the
NICAM or FM-identification parameters must be read
and evaluated by the controller in order to enable
appropriate switching of the channel select matrix of
the baseband processing part. The FM-identification
registers are described in Section 6.6.1.
To handle the
NICAM-sound and to observe the NICAM-quality, at
least the registers C_AD_BITS and ERROR_RATE
must be read and evaluated by the controller. Addi-
tional data bits and CIB bits, if supplied by the NICAM
transmitter, can be obtained by reading the registers
ADD_BITS and CIB_BITS.
6.4.1. NICAM Mode Control/Additional Data Bits
Register
NICAM operation mode control bits and A[2:0] of the
additional data bits.
Format:
Important:
“
S
”
= bit[0] indicates correct NICAM-syn-
chronization (S = 1). If S = 0, the MSP 3415/3455G
has not yet synchronized correctly to frame and
sequence, or has lost synchronization. The remaining
read registers are therefore not valid. The MSP mutes
the NICAM output automatically and tries to synchro-
nize again as long as MODE_REG[6] is set.
The operation mode is coded by C4-C1 as shown in
Table 6
–
16.
Note:
It is no longer necessary to read out and evalu-
ate the C_AD_BITS. All evaluation is performed in the
MSP and indicated in the STATUS register.
6.4.2. Additional Data Bits Register
Contains the remaining 8 of the 11 additional data bits.
The additional data bits are not yet defined by the
NICAM 728 system.
