Functional Description
Figure 21
Functional Diagram of the Tone Generator
Distinctive alerting signals, allowing for example the use of different multitone ringing
patterns, are all programmable using the beat tone generator in conjunction with the
square/trapezoid generator. In the case of two or three tone ringing signals, the square/
trapezoid generator controls the output frequency pitch whilst the beat generator
controls the repetition rate. Either square or trapezoid shaped tones can be generated
depending on the TGCR.SQTR bit setting. If the piezo mode (PM or TRL in TGSR) is
V
chosen, only a square-wave is available (fixed amplitude of
). In this case the SQTR
DD
bit in TGCR has no effect.
A secondary trapezoid generator is also built into the ARCOFI. Depending on the DT-bit
setting in the TGCR, the output signal of this generator is added to the output signal of
the Square/Trapezoid (S/T) generator. In conjunction with the S/T generator, a wide
variety of different dual tone signals can be programmed.
If the beat generator (TGCR.BT = 1) is enabled, the automatic stop function (SM-bit
setting in TGCR) can be activated. This prevents an uncontrolled turn-off of the tone
generator. Only when the generation of the frequency F2 or F3 (depending on the BM-bit
setting in TGCR) has been completed, the tone generator will switch off.
