__STATIC_INLINE void LL_RCC_MSI_DisablePLLMode

(

void

)

Disable MSI-PLL mode.

Note

cleared by hardware when LSE is disabled (LSEON = 0) or when the Clock Security System on LSE detects a LSE failure CR MSIPLLEN LL_RCC_MSI_DisablePLLMode

Return values

None

Definition at line 2533 of file stm32l4xx_ll_rcc.h.

{
