When active, the internal FM mono sound
demodulator can handle excessive FM deviations up
to 400 kHz. This might happen in D/K standard China.
To activate this mode, it is mandatory to set
D/K standard first. The sound output level has to be
adapted accordingly by the microprocessor to avoid
sound DAC clipping. E.g. for 400 kHz FM deviation,
the
12 dB setting of the sound level register
(see Table 39) is recommended.
