This flag (output on IRQ pin) is set to ON by the AUTOSTD when the standard recognition status
has changed. The external microprocessor will detect this signal and will run the OSD procedure.
This procedure must first reset via I²C the IRQ flag and then read the detection status in the
registers (NICAM_STAT, ZWT_STAT, AUTO_STAT and CH_MX)
Single Shot Mode Selection
0: Single Shot mode is not selected
1: Single Shot mode is selected
Selects FM deviation configuration to take into account of overmodulation in DK_NICAM standard.
00: FM 50 kHz (Default)
01: FM 200 kHz
Makes exclusive the auto search of DK/K1/K2/K3 and L/L’ standard
0: DK/K1/K2/K3 standard auto-search / L/L’ disabled
1: L/L’ standard auto-search / DK/K1/K2/K3 disabled
Displays the Absolute Peak Level of the audio source selected. The measured value is
updated continuously every 64 ms. The range varies linearly from the full scale (0 dB) down to
1/256 of the full scale (-48 dB).
