(2) Musical Note Code
The first byte of music data code is where a user can define musical note code. Table 8.4 shows musical notes and
their corresponding note codes (L5 to L0). When all bits are set to “0”, the duration or beat of the note is identical
to that of the code with L0 alone set to “1” (1/64).
