AFCD3[7:0] (Addr.: 7DH): AFI Filter Coefficient Data 3
AUXCOEF[9:2]
The following read registers contain channel individual values. The channel
number defined in register CTRLTSMON.MCH[4:0]
Since MVAL is the interrupt source indicating an update of the monitor registers it must
be reset after the monitor registers are read out in order to avoid an unwanted interrupt.
MONSI[7:0] (Addr.: 29H): Monitor send input signal (A-/µ-Law encoded)
The content of this register is PCM encoded.
