Melodies are programmed by writing data to the
note RAM and scale RAM.
Each word in the note RAM and scale RAM
represents a note or rest and it corresponds
between two RAMs one to one. In other words, the
data stored in the same low-order 8-bit address of
the note and scale RAMs correspond to a note on
the musical score.
Melody data should be written from the start
address of each RAM continuously by notes.
Note: The melody RAM cannot be rewritten while
a melody is playing.
s Setting the note RAM
First, the following describes data to be set in the
note RAM.
(1) Note (note RAM: D7 to D5)
The 3 high-order bits (D7 to D5) in the note
RAM specify a type of note or rest. Table
5.13.2.1 shows the correspondence between the
setting value and note/rest.

Rest
A length of sound shorter than a sixteenth note
that is not included in the table above may be
specified using two available notes and the tie
bit.
(2) Tie (note RAM: D4)
When the D4 bit in the note RAM is set to "1", a
silent period of approximately 10 msec will be
inserted between the previous and concerned
notes for playing discretely between notes.
When the D4 bit is set to "0", no silent period
will be inserted, and the previous and
concerned notes will play continuously. This is
used to specify a tie. The notes to be tied must
be the same pitch and the D4 bit cannot be used
to specify a slur.
Do not specify a tie (do not set the D4 bit in the
note RAM to "0") for the note beginning a
melody. Writing "0" may cause improper
operation as there is no previous note.
(3) Rest (note RAM: D3)
When the D3 bit in the note RAM is set to "1",
the data at that address is assumed as a rest and
a break time with the length specified using the
D7 to D5 bits will be inserted. When the D3 bit
is set to "0", the data will be played as a note.
When specifying a rest, set 00H or an available
scale data to the corresponding scale RAM
address. Writing FFH may cause improper
operation.
(4) END (note RAM: D2)
Set "1" to the D2 bit in the note RAM, if that
address is the last note or rest of a melody. This
bit controls the end of play. The D2 bits in the
middle of a melody must be set to "0".
