impl Ccipr1

pub const fn usart1sel(&self) -> Usart1sel

USART1 kernel clock source selection This bits are used to select the USART1 kernel clock source. Access can be secured by GTZC_TZSC USART1SEC. When secure, a non-secure read/write access is RAZ/WI.

pub const fn lptim2sel(&self) -> Lptim2sel

Low-power timer 2 kernel clock source selection These bits are used to select the LPTIM2 kernel clock source. Access can be secured by GTZC_TZSC LPTIM2SEC. When secure, a non-secure read/write access is RAZ/WI. It does not generate an illegal access interrupt. This bit can be protected against unprivileged access when secure with RCC SPRIV or when non-secure with RCC NSPRIV. Note: The LPTIM2 is functional in Stop 0 and Stop 1 mode only when the kernel clock is LSI, LSE or HSI if HSIKERON = 1.

pub fn set_lptim2sel(&mut self, val: Lptim2sel)
