23.3 Description of Operation
23.3.1
A buzzer sound is output in the following procedure.
(1) Select a buzzer output mode using the buzzer 0 tempo code register (MD0TMP).
(2) Select a duty of the High level width of the buzzer output waveform using the buzzer 0 tone length code register
(3) Set the buzzer output frequency in the buzzer 0 scale code register (MD0TON).
(4) Set bit 2 (ENMLT) of the frequency control register 1(FCON1) to “1” to enable the 2×low-speed clock.
(5) When the M0RUN bit of the buzzer 0 control register (MD0CON) is set to “1”, the waveform equivalent to the
