Disable MSI oscillator CR MSION LL_RCC_MSI_Disable.

Return values:

None

Definition at line 1197 of file stm32l4xx_ll_rcc.h.

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 1233 of file stm32l4xx_ll_rcc.h.

Enable MSI oscillator CR MSION LL_RCC_MSI_Enable.

Return values:

None

Definition at line 1187 of file stm32l4xx_ll_rcc.h.

Enable MSI PLL-mode (Hardware auto calibration with LSE)

Note:

Return values:

None

Definition at line 1221 of file stm32l4xx_ll_rcc.h.

Enable MSI clock range selection with MSIRANGE register.

Note:
