With the saturation unit additional gain GS can be added to the output signal. This will
cause the signal to exceed the maximum value of the internal representation so that the
peaks will be cut off. This induces more harmonics to make a tone sound louder.
The tone generator unit has two outputs (S
can be programmed individually by the preceding gain stages (GO
Additionally to S
frontend exists.This direct output is the most significant bit of S
path, the tone generator must be set to square wave generation (TGCTL.WF = 1).
If TGCTL.E16 = 0, the output of the tone generator is limited to 4 kHz maximum output
frequency of the harmonics. This is normal telephone quality and corresponds to 8 kHz
sample frequency. If direct output to the AFE loudspeaker amplifier is used, it may be
desired to rise the frequency limit. With TGCTL.E16 = 1, the output of the tone generator
is limited to 8kHz maximum output frequency of the harmonics, which corresponds to
16 kHz sample frequency. This allows to use more frequencies at the direct output but
the normal outputs S
