(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(X
IN
) = 4.19 MHz into about
2 kHz (2048 Hz) is output from the P5

/CNTR
0
pin.
The level of the P5

/CNTR
0
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.
