Chapter 20 Melody Driver
20.3.4 Scale Codes
A scale code is set in the melody 0 scale code register (MD0TON).
In the melody driver, a frequency that can be output is expressed by the following equation.
The bit correspondence between TN and scale codes is expressed by the following equation.
Table 20-3 shows the correspondence between scales and scale codes.
When the M0TN6 to M0TN2 bits are set to "0", scale becomes a rest. The rest length is set by the tone length code
(MD0LEN).
TN = 2
( TN + 1 )
