Tone Gen
The Tone Gen page controls the digital tone generator at the input to the
DAC. TONE GEN CFG1 panel starts the tone generator and enables a DTMF
tone if required. TONE GEN CFG2 panel sets the gain applied to the tone and
controls which sine-wave generator is used (or both). The TONE GEN FREQ
panels set the frequency for the two generators as described in the datasheet.
The DTMF Phone pad panel produces DTMF tones when the buttons are
pressed. The TONE GEN CYCLES panel controls how many beeps are
produced, and the TONE GEN ON and OFF PER panels control the on and
off periods.
