Fractional divider line missing from CubeMX generated LL library code

[decalvus]

Hi

I’m using CubeMX 6.12.0 with a STM32U5G7VJT6Q project.
When using a fractional divider setting for PLL3 (in the RCC System Clock configuration), CubeMX generates the below LL library code.
The LL_RCC_PLL3FRACN_Enable() is correctly included, but it seems the fractional divider line (e.g. LL_RCC_PLL3_SetFRACN(1024)) is missing from the generated code.
When switching to HAL it is included correctly.

void PeriphCommonClock_Config(void)
{
  LL_RCC_PLL3_ConfigDomain_HSPI_LTDC(LL_RCC_PLL3SOURCE_HSE, 1, 9, 5);
  LL_RCC_PLL3_EnableDomain_HSPI_LTDC();
  LL_RCC_PLL3_SetVCOInputRange(LL_RCC_PLLINPUTRANGE_8_16);
  LL_RCC_PLL3_Enable();
   /* Wait till PLL3 is ready */
  while(LL_RCC_PLL3_IsReady() != 1)
  {
  }
  LL_RCC_PLL3FRACN_Enable();
}

Hello @decalvus 

Could you please add your .ioc file so we can be able to test you case.

Hello @decalvus 

This behavior has been solved on the last version of the STM32CubeMX V6.13.0.

Best Regards.
