Stereo Mode Detection flag activated when a stereo standard coming from the demodulator
selected on Loudspeaker output. Stereo transmission modes are:
- Zweiton stereo (ZWT_DET&ST&DM = 110, indifferently German or Korean standard)
- NICAM stereo with backup (CBI = 1000)
- NICAM stereo with no backup (CBI = 0000)
The stereo flag is also output on ST pin to control an external indicator (an LED, for instance)
When AUTOSTD is ON and a standard has been detected, the FSM has two “stable states”. These
flags indicate whether the FSM is in the state “mono-det” (mono standard detected) or “stereo-det”
(stereo standard detected). If at least one stereo standard is enabled, the “mono-det” state is only
transitory.
