The timer mode is used to make the buzzer ring. Figure 3.4.1 shows the operation timing, and
Figure 3.4.2 shows the set-up procedure.
Use the following peripheral function:
• The pulse-outputting function in timer mode of timer A.
(1) Sound a 2-kHz buzz beep by use of timer A0.
(2) Effect pull-up in the relevant port by use of a pull-up resistor. When the buzzer is off, set the
(3) Connect a 16-MHz oscillator to X
(1) The microcomputer begins performing a count on timer A0. Timer A0 has disabled interrupts.
(2) The microcomputer begins pulse output by setting the pulse output function select bit to
(3) The microcomputer stops outputting pulses by setting the pulse output function select bit to
port high-impedance, and stabilize the potential resulting from pulling up.
