Implementations

impl Pll2fracr

pub const fn pllfracn(&self) -> u16

Fractional part of the multiplication factor for PLL2 VCO Set and reset by software to control the fractional part of the multiplication factor of the VCO. These bits can be written at any time, allowing dynamic fine-tuning of the PLL2 VCO. VCO output frequency = Fref2_ck x (PLL2N + (PLL2FRACN / 213)), with PLL2N must be between 4 and 512. PLL2FRACN can be between 0 and 213 - 1. The input frequency Fref2_ck must be between 4 and 16 MHz. In order to change the FRACN value on-the-fly even if the PLL is enabled, the application must proceed as follows: Set the bit PLL2FRACEN to 0. Write the new fractional value into PLL2FRACN. Set the bit PLL2FRACEN to 1.

Trait Implementations

impl Clone for Pll2fracr

fn clone(&self) -> Pll2fracr

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Pll2fracr

fn default() -> Pll2fracr

Returns the “default value” for a type.

impl PartialEq for Pll2fracr

fn eq(&self, other: &Pll2fracr) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
