Implementations

impl Pll1fracr

pub const fn pllfracn(&self) -> u16

Fractional part of the multiplication factor for PLL1 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 PLL1 VCO. VCO output frequency = F_{ref1_ck} x [multiplication factor for PLL1 VCO + (PLL1FRACN / 2¹³)], with: Multiplication factor for PLL1 VCO must be between 4 and 512. PLL1FRACN can be between 0 and 2¹³- 1. The input frequency F_{ref1_ck} must be between 4 and 16 MHz. To change the used fractional value on-the-fly even if the PLL1 is enabled, the application must proceed as follows: Set the bit PLL1FRACEN to 0. Write the new fractional value into PLL1FRACN. Set the bit PLL1FRACEN to 1.

Trait Implementations

impl Clone for Pll1fracr

fn clone(&self) -> Pll1fracr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Pll1fracr

fn default() -> Pll1fracr

Returns the “default value” for a type.

impl PartialEq for Pll1fracr

fn eq(&self, other: &Pll1fracr) -> bool

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

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

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