Implementations

impl W

pub fn md_mbs(&mut self) -> MD_MBS_W<'_>

Bit 0 - input word of the wrapper bit 32.

pub fn md_req(&mut self) -> MD_REQ_W<'_>

Bit 1 - md change request.

pub fn mf(&mut self) -> MF_W<'_>

Bits 2:4 - programmable modulation frequency fm = Fref/Nss mf[2:0] = 000 => Nss=512 (fm ~ 3.

pub fn mr(&mut self) -> MR_W<'_>

Bits 5:7 - 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.

pub fn mc(&mut self) -> MC_W<'_>

Bits 8:9 - 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.

pub fn mdiv_ext(&mut self) -> MDIV_EXT_W<'_>

Bits 10:25 - to select an external mdiv value.

pub fn mreq(&mut self) -> MREQ_W<'_>

Bit 26 - to select an external mreq value.

pub fn dither(&mut self) -> DITHER_W<'_>

Bit 27 - 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.

pub fn sel_ext(&mut self) -> SEL_EXT_W<'_>

Bit 28 - to select mdiv_ext and mreq_ext sel_ext = 0: mdiv ~ md[32:0], mreq = 1 sel_ext = 1 : mdiv = mdiv_ext, mreq = mreq_ext.
