PLL0 Spread Spectrum Wrapper control register 1
DITHER_R | Field DITHER reader - dithering between two modulation frequencies in a random way or in a pseudo random way (white noise), in order to decrease the probability that the modulated waveform will occur with the same phase on a particular point on the screen.
|
DITHER_W | Field DITHER writer - dithering between two modulation frequencies in a random way or in a pseudo random way (white noise), in order to decrease the probability that the modulated waveform will occur with the same phase on a particular point on the screen.
