Notes
The TDA9874H 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 that case the program of the first sound
carrier is selected for reproduction, independent of bit AMUTE being set or not.

NICAM application control bits.
These bits correspond to the control bits C1 to C4 in
the NICAM transmission.
Synchronization bit.
OSB = 1, indicates that the device has both frame and C0
(16 frame) synchronization. OSB = 0, indicates the audio output from the NICAM part is
digital silence.
Configuration change.
CFC = 1, indicates a configuration change at the 16 frame (C0)
boundary.
Identification of NICAM stereo.
S/MB = 1, indicates stereo mode.
Identification of NICAM dual mono.
D/SB = 1, indicates dual mono mode.
