Tone Filter
A programmable tone filter can be switched in the tone signal path by setting the ETF
(Enable Tone Filter) bit. The tone filter contains a programmable equalizer and a
saturation amplifier (see figure Chapter •).
A generated square-wave or trapezoid signal can be converted by the equalizer into a
sine-wave signal. The equalizer is realized as a band-pass filter. The filter parameters
