4.3.3
Controlling of the generated tone follows the setting of the control bits ET (Enable Tone)
and PT (Pulsed Tone) and the CRAM parameters TON and TOFF corresponding table
14 and table 15.

Four typical examples for the control generator programming are shown in Figure 61.
In the automatic stop mode (TGCR.SM = ’1’) the selected tone sequence is only stopped
after a sequence is completed. This avoids unpleasant sounds when stopping the tone
generator.
The tone signal can be fed directly to the input of the loudspeaker amplifier by setting the
TGSR.TRL bit to ’1’. In this mode only a square wave (fixed amplitude of VDD) is
available from the signal generators (F1, F2, F3)and the TGCR.SQTR bit has no effect.
