impl Cr

pub const fn wucksel(&self) -> Wucksel

Wakeup clock selection. 10x: ck_spre (usually 1 Hz) clock is selected in BCD mode. In binary or mixed mode, this is the clock selected by BCDU. 11x: ck_spre (usually 1 Hz) clock is selected in BCD mode. In binary or mixed mode, this is the clock selected by BCDU. Furthermore, 2¹⁶ is added to the WUT counter value.

pub fn set_wucksel(&mut self, val: Wucksel)

Wakeup clock selection. 10x: ck_spre (usually 1 Hz) clock is selected in BCD mode. In binary or mixed mode, this is the clock selected by BCDU. 11x: ck_spre (usually 1 Hz) clock is selected in BCD mode. In binary or mixed mode, this is the clock selected by BCDU. Furthermore, 2¹⁶ is added to the WUT counter value.
