I am using an STM32H743IIT6. In SYSCFG_PMCR, the BOOSTE bit states that '1' must be set if the voltage is below 2.7V. So, which voltage is it—VDD, VDDA, or some other voltage? I’m analyzing some documentation on an ADC, and it mentions those bits. Is there any issue with setting BOOSTE to '1' when the voltage is greater than 2.7V? Could long-term operation under these conditions cause damage to the chip?

The device may be damaged if the BOOST bits are set to '1' while the voltage is > 2.7V
