Implementations

impl Cfgr4

pub const fn hpre5(&self) -> Hpre5

AHB5 prescaler when SWS select PLL1 Set and cleared by software to control the division factor of the AHB5 clock (hclk5). Must not be changed when SYSCLK source indicated by SWS is PLL1. When SYSCLK source indicated by SWS is not PLL1: HPRE5 is not taken into account. When SYSCLK source indicated by SWS is PLL1: HPRE5 is taken into account, from the moment the system clock switch occurs Depending on the device voltage range, the software must set these bits correctly to ensure that the AHB5 frequency does not exceed the maximum allowed frequency (for more details, refer to Table�99: SYSCLK and bus maximum frequency). After a write operation to these bits and before decreasing the voltage range, this register must be read to be sure that the new value is taken into account. 0xx: hclk5 = SYSCLK not divided

pub fn set_hpre5(&mut self, val: Hpre5)

AHB5 prescaler when SWS select PLL1 Set and cleared by software to control the division factor of the AHB5 clock (hclk5). Must not be changed when SYSCLK source indicated by SWS is PLL1. When SYSCLK source indicated by SWS is not PLL1: HPRE5 is not taken into account. When SYSCLK source indicated by SWS is PLL1: HPRE5 is taken into account, from the moment the system clock switch occurs Depending on the device voltage range, the software must set these bits correctly to ensure that the AHB5 frequency does not exceed the maximum allowed frequency (for more details, refer to Table�99: SYSCLK and bus maximum frequency). After a write operation to these bits and before decreasing the voltage range, this register must be read to be sure that the new value is taken into account. 0xx: hclk5 = SYSCLK not divided

pub const fn hdiv5(&self) -> Hdiv5

AHB5 divider when SWS select HSI or HSE Set and reset by software. Set to 1 by hardware when entering Stop 1 mode. When SYSCLK source indicated by SWS is HSI or HSE: HDIV5 is taken into account When SYSCLK source indicated by SWS is PLL1: HDIV5 is taken not taken into account Depending on the device voltage range, the software must set this bit correctly to ensure that the AHB5 frequency does not exceed the maximum allowed frequency (for more details, refer to Table�99). After a write operation to this bit and before decreasing the voltage range, this register must be read to be sure that the new value is taken into account.

pub fn set_hdiv5(&mut self, val: Hdiv5)

AHB5 divider when SWS select HSI or HSE Set and reset by software. Set to 1 by hardware when entering Stop 1 mode. When SYSCLK source indicated by SWS is HSI or HSE: HDIV5 is taken into account When SYSCLK source indicated by SWS is PLL1: HDIV5 is taken not taken into account Depending on the device voltage range, the software must set this bit correctly to ensure that the AHB5 frequency does not exceed the maximum allowed frequency (for more details, refer to Table�99). After a write operation to this bit and before decreasing the voltage range, this register must be read to be sure that the new value is taken into account.

Trait Implementations

impl Clone for Cfgr4

fn clone(&self) -> Cfgr4

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Cfgr4

fn default() -> Cfgr4

Returns the “default value” for a type.

impl PartialEq for Cfgr4

fn eq(&self, other: &Cfgr4) -> 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.
