23.3.6
A buzzer sound is output in the following procedure.
(1) Select a buzzer mode by setting the BZMD bit of the melody 0 control register (MD0CON) to “1”.
(2) Select a buzzer output mode using the melody 0 tempo code register (MD0TMP).
(3) Select a duty of the High level width of the buzzer output waveform using the melody 0 tone length code register
(4) Set the buzzer output frequency in the melody 0 scale code register (MD0TON).
(5) Set bit 2 (ENMLT) of the frequency control register 1(FCON1) to “1” to enable the 2×low-speed clock.
(6) When the M0RUN bit of the melody 0 control register (MD0CON) is set to “1”, the waveform equivalent to the
Figure 23-4 shows the output waveform of each buzzer output mode.
(MD0LEN).
buzzer sound that is set from the MD0 pin is output.
