Reference Manual to LL API cross reference (Register Field Functions)

SYSCFG_CFGR1 ANASWVDD LL_SYSCFG_DisableAnalogSwitchVdd

Note

I/O analog switches are supplied by VDDA or booster when booster in on. Dedicated voltage booster (supplied by VDD) is the recommended configuration with low VDDA voltage operation.

void LL_SYSCFG_EnableAnalogBooster ( void )

Enable I/O analog switch voltage booster.

Reference Manual to LL API cross reference (Register Field Functions)

SYSCFG_CFGR1 BOOSTEN LL_SYSCFG_EnableAnalogBooster

Note

When voltage booster is enabled, I/O analog switches are supplied by a dedicated voltage booster, from VDD power domain. This is the recommended configuration with low VDDA voltage operation.
