CSS on LSE enable Set by software to enable the CSS on LSE. LSECSSON must be enabled after the LSE oscillator is enabled (LSEON bit enabled) and ready (LSERDY flag set by hardware), and after the RTCSEL bit is selected. Once enabled, this bit cannot be disabled, except after a LSE failure detection (LSECSSD = 1). In that case, the software must disable the LSECSSON bit.

pub const fn lsesysen(&self) -> bool
pub const fn lsesysen(&self) -> bool
LSE system clock (LSESYS) enable Set by software to enable always the LSE system clock generated by RCC. This clock can be used by any peripheral when its source clock is the LSE or at system level in case of one of the LSCOSEL, MCO, MSI PLL mode or CSS on LSE is needed. The LSESYS clock can be generated even if LSESYSEN= 0 if the LSE clock is requested by the CSS on LSE, by a peripheral or any other source clock using LSE.
