(3) Timer application example 2 : Piezoelectric buzzer output
Outline : The rectangular waveform output function of a timer is applied for a piezoelectric buzzer
output.
Specifications : The rectangular waveform resulting from dividing clock f(XIN) = 4.19 MHz into about
2 kHz (2048 Hz) is output from the P54/CNTR0 pin.
The level of the P54/CNTR0 pin fixes to “H” while a piezoelectric buzzer output is
stopped.
Figure 2.2.13 shows an example of a peripheral circuit, and Figure 2.2.14 shows a connection of the
timer and setting of the division ratio.
