RCC_PLLSOURCE_HSE: HSE
oscillator clock selected as PLL
clock entry
Notes:
This function must be used only when
the main PLL is disabled.
__HAL_RCC_PLL_PLLM_CONFIG
Description:
Macro to configure the PLL
multiplication factor.
Parameters:
__PLLM__: specifies the division factor
for PLL VCO input clock This parameter
must be a number between Min_Data =
2 and Max_Data = 63.
Notes:
This function must be used only when
the main PLL is disabled.
You have to set the PLLM parameter
correctly to ensure that the VCO input
frequency ranges from 1 to 2 MHz. It is
recommended to select a frequency of 2
MHz to limit PLL jitter.
