pub const fn msison(&self) -> bool

MSIS clock enable Set and cleared by software. Cleared by hardware to stop the MSIS oscillator when entering Stop, Standby or Shutdown mode. Set by hardware to force the MSIS oscillator ON when exiting Standby or Shutdown mode. Set by hardware to force the MSIS oscillator ON when STOPWUCK = 0 when exiting Stop modes or in case of a failure of the HSE oscillator. Set by hardware when used directly or indirectly as system clock.

Keeping the MSI ON in Stop mode allows the communication speed not to be reduced by the MSI startup time. This bit has no effect on MSISON and MSIKON values (see autonomous mode for more details). The MSIKERON must be configured at 0 before entering Stop 3 mode.

Keeping the MSI ON in Stop mode allows the communication speed not to be reduced by the MSI startup time. This bit has no effect on MSISON and MSIKON values (see autonomous mode for more details). The MSIKERON must be configured at 0 before entering Stop 3 mode.

pub const fn msisrdy(&self) -> bool
