STM32G0B0: No PLLPCLK output on RCC_MCO2

[ADESC.2]

Hello everyone.

The case may be known, but if it helps...

After activating the Master Clock Output (1 or 2) in STM32CubeIDE on PLLP, no signal is present on RCC_MCO output.
After analysis the PLL must be activated by adding the initialization in a User Code if no device dependent on this PLL is used (ADC, I2S1 or I2S2):
__HAL_RCC_PLLCLKOUT_ENABLE(RCC_PLLPCLK);

Regards.
