impl Cfgr1

pub const fn sw(&self) -> Sw

system clock switch Set and cleared by software to select system clock source (SYSCLK). Configured by hardware to force MSIS oscillator selection when exiting Standby or Shutdown mode. Configured by hardware to force MSIS or HSI oscillator selection when exiting Stop mode or in case of HSE oscillator failure, depending on STOPWUCK value.

pub fn set_sw(&mut self, val: Sw)

system clock switch Set and cleared by software to select system clock source (SYSCLK). Configured by hardware to force MSIS oscillator selection when exiting Standby or Shutdown mode. Configured by hardware to force MSIS or HSI oscillator selection when exiting Stop mode or in case of HSE oscillator failure, depending on STOPWUCK value.

pub const fn sws(&self) -> Sw

system clock switch status Set and cleared by hardware to indicate which clock source is used as system clock.

pub fn set_sws(&mut self, val: Sw)

system clock switch status Set and cleared by hardware to indicate which clock source is used as system clock.

pub const fn stopwuck(&self) -> Stopwuck

wakeup from Stop and CSS backup clock selection Set and cleared by software to select the system clock used when exiting Stop mode. The selected clock is also used as emergency clock for the clock security system on HSE. Warning: STOPWUCK must not be modified when the CSS is enabled by HSECSSON bit in RCC_CR and the system clock is HSE (SWS = 10) or a switch on HSE is requested (SW = 10).

pub fn set_stopwuck(&mut self, val: Stopwuck)

wakeup from Stop and CSS backup clock selection Set and cleared by software to select the system clock used when exiting Stop mode. The selected clock is also used as emergency clock for the clock security system on HSE. Warning: STOPWUCK must not be modified when the CSS is enabled by HSECSSON bit in RCC_CR and the system clock is HSE (SWS = 10) or a switch on HSE is requested (SW = 10).

pub const fn stopkerwuck(&self) -> Stopkerwuck

wakeup from Stop kernel clock automatic enable selection Set and cleared by software to enable automatically another oscillator when exiting Stop mode. This oscillator can be used as independent kernel clock by peripherals.

pub fn set_stopkerwuck(&mut self, val: Stopkerwuck)

wakeup from Stop kernel clock automatic enable selection Set and cleared by software to enable automatically another oscillator when exiting Stop mode. This oscillator can be used as independent kernel clock by peripherals.

pub const fn mcosel(&self) -> Mcosel

microcontroller clock output Set and cleared by software. Others: reserved Note: This clock output may have some truncated cycles at startup or during MCO clock source switching.

pub fn set_mcosel(&mut self, val: Mcosel)

microcontroller clock output Set and cleared by software. Others: reserved Note: This clock output may have some truncated cycles at startup or during MCO clock source switching.

pub const fn mcopre(&self) -> Mcopre

microcontroller clock output prescaler Set and cleared by software. It is highly recommended to change this prescaler before MCO output is enabled. Others: not allowed

pub fn set_mcopre(&mut self, val: Mcopre)

microcontroller clock output prescaler Set and cleared by software. It is highly recommended to change this prescaler before MCO output is enabled. Others: not allowed
