Product specification
Digital TV Sound Processor (DTVSP)
TDA9875A
10.4.2
NICAM
STATUS REGISTER
The TDA9875A 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 to logic 1, 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.

Subaddress 1
10.4.3
NICAN
ERROR COUNT REGISTER
Bits B7 to B0 contain the number of errors occurring in the previous 128 ms period. The register is updated every 128 ms.
