low-speed clock (32.768kHz) and outputs the signals from the MLDALM pin.
Operational Description
The Melody function generates signals of any frequency (4Hz-5461Hz) based on a
The melody tone can easily be heard by connecting an external loud speaker.

(Refer: Basic musical scale setting table)
to be output from MLDALM. The melody output frequency must then be set to 12-bit
register MELFH, MELFL.
Melody generator
MELALMC<MELALM> must first be set as 1 in order to select the melody waveform
The following are examples of settings and calculations of melody output frequency.
