13.10 Buzzer
The buzzer output is made at the MD/MDP pins or the DACOUT/AOUT pins when the phrase
with the buzzer setting is started from the interface circuit. Buzzer output is available when
the frequency and sound type have been set in the phrase address management area.
Inputting the stop code will stop the buzzer output.
Based on the settings made in the phrase management area, the buzzer output frequency
can be selected from the 50% duty ratio frequencies of 0.5 kHz, 1.0 kHz, and 2.0 kHz, and
the buzzer output mode can be selected from intermittent tone 1, intermittent tone 2, single
tone, and continuous tone.
The output waveforms in the different output modes is shown in Figure 13-7. The dark filled
parts in the waveform indicate the output frequency signal (0.5, 1.0, or 2.0 kHz).
