MELODY ASSEMBLER MLA628X
S1C62 FAMILY EPSON IV-5
DEVELOPMENT TOOL REFERENCE MANUAL
(3) Scale field
The scale field can be filled in with any scale (C3 through C6#).
When inputting the scale data directly, prefix the data with "$". In this case, the input data range is 00H
through FDH.
Moreover, the rest may be selected by describes "RR" in the scale field.
The number of specifiable scales varies depending on the model.
(Refer to the "S5U1C62N8xD Manual".)
(4) End bit field
The instruction indicating the end of the melody is written in the end bit field. When "1" is written, the
melody finishes with the melody data of that address. Otherwise, write "0", or omit it altogether.
(5) Comment field
Any comment, such as the program index or processing details, can be written in the comment field,
with no affect on the object file created with the assembler.
The comment field is the area between the semicolon ";" and the CR code at the end of the line.
A line can be made up of a comment field alone. However, if the comment extends into two or more
lines, each line must be headed with a semicolon.

Correspondence between scale and scale data
The scale or scale data written in the scale
field is loaded into the scale ROM, and the
address of the loaded scale data becomes
the scale address data.
Table 4.2.4
Correspondence between notes and note data
The correspondence between notes and
note data are as follows.
