2.4 Generating Register Coefficients Using PPC3

PPC3 is recommended to generate register values for all forms of tone generation configurations. This section uses SG1 amplitude and frequency configuration as an example to generate I2C scripts.

The mixing volume coefficient and this gain formula configure SG1 and SG2 amplitudes. Fill in coefficient values in the GUI boxes like Figure 2-2 suggests. This applies to all tone generators.

I2C script generation can be accessed offline in PPC3 without connecting a device to the software.
