PLL0 Spread Spectrum Wrapper control register 1

Structs

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.

MC_R

Field MC reader - modulation waveform control Compensation for low pass filtering of the PLL to get a triangular modulation at the output of the PLL, giving a flat frequency spectrum.

MC_W

Field MC writer - modulation waveform control Compensation for low pass filtering of the PLL to get a triangular modulation at the output of the PLL, giving a flat frequency spectrum.

MDIV_EXT_R

Field MDIV_EXT reader - to select an external mdiv value.

MDIV_EXT_W

Field MDIV_EXT writer - to select an external mdiv value.

MD_MBS_R

Field MD_MBS reader - input word of the wrapper bit 32.

MD_MBS_W

Field MD_MBS writer - input word of the wrapper bit 32.

MD_REQ_R

Field MD_REQ reader - md change request.

MD_REQ_W

Field MD_REQ writer - md change request.

MF_R

Field MF reader - programmable modulation frequency fm = Fref/Nss mf[2:0] = 000 => Nss=512 (fm ~ 3.

MF_W

Field MF writer - programmable modulation frequency fm = Fref/Nss mf[2:0] = 000 => Nss=512 (fm ~ 3.

MREQ_R

Field MREQ reader - to select an external mreq value.

MREQ_W

Field MREQ writer - to select an external mreq value.

MR_R

Field MR reader - programmable frequency modulation depth Dfmodpk-pk = Frefkss/Fcco = kss/(2md[32:25]dec) mr[2:0] = 000 => kss = 0 (no spread spectrum) mr[2:0] = 001 => kss ~ 1 mr[2:0] = 010 => kss ~ 1.

MR_W

Field MR writer - programmable frequency modulation depth Dfmodpk-pk = Frefkss/Fcco = kss/(2md[32:25]dec) mr[2:0] = 000 => kss = 0 (no spread spectrum) mr[2:0] = 001 => kss ~ 1 mr[2:0] = 010 => kss ~ 1.
