Table 97 Description of Table 96
10.4.2.3
The TDA9875 does not support the Extended Control Modes. Therefore, the program of the first sound carrier
(i.e. FM mono or AM) is selected for reproduction in case bit C3 is set HIGH, independent of bit AMUTE in the NICAM
configuration register being set or not.
When a NICAM transmitter is switched off, the device will lose synchronization. In this situation the program of the first
sound carrier is selected for reproduction, independent of bit AMUTE being set or not.
10.4.3
10.4.3.1
Bits B7 to B0 contain the number of errors occurring in the previous 128 ms period. The register is updated every 128 ms.

if this bit is HIGH it indicates dual mono mode
if this bit is HIGH it indicates stereo mode
if this bit is HIGH, it indicates a configuration change at the 16 frame (C0)
boundary
indicates that the device has both frame and C0 (16 frame) synchronization
the audio output from the NICAM part should be digital silence
these bits correspond to the control bits C1 to C4 in the NICAM transmission
