Frame frequency calculation
For DMode[1:0] = ‘00’
where
for default values of SSD1298
Fosc = ~510KHz, DIV[1:0] = ‘00’, RTN[3:0] = 8, MUX[8:0] = 319, VBP[7:0] = 3, VFP[7:0] = 1,
Frame frequency =
Power Control 2 (R0Ch) (POR = 0004h)
VRC[2:0]: Adjust VCIX2 output voltage. The adjusted level is indicated in the chart below VRC2-0 setting.

Fosc = internal oscillator frequency
div = Division ratio determined by DIV[1:0]
rtn = RTN[3:0]
mux = MUX[8:0]
