(2) Musical Note Code

The first byte of music data code is where a user can define musical note code. Table 7.4 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).
