23.3.3
A tone length code is set in the melody 0 tone length code register (MD0LEN).
Table 23-2 shows the correspondence between tone lengths and tone length codes.
The tone length when all the bits are set to "0" is equal to the shortest tone length (the tone length when the only M0LN0
bit is set to "1").
The tone length set by a tone length code and a tempo code is expressed by the following equation.
where TP is an integer of 1 to 15, and LN is an integer of 1 to 63.
The bit correspondence between TP and tempo codes is expressed by the following equation.
The bit correspondence between LN and tone length codes is expressed by the following equation.
Tone length = 1.953125 × ( TP + 1 ) × ( LN + 1 ) ms
TP = 2
LN = 2
