Function Documentation

__STATIC_INLINE void LL_SYSCFG_ClearFlag_SP ( void   )

Clear SRAM2 parity error flag SYSCFG_CFGR2 SPF LL_SYSCFG_ClearFlag_SP.

Return values:
None

Definition at line 854 of file stm32l4xx_ll_system.h.

__STATIC_INLINE void LL_SYSCFG_DisableAnalogBooster ( void   )

Disable I/O analog switch voltage booster.

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.
The I/O analog switch voltage booster is relevant for peripherals using I/O in analog input: ADC, COMP, OPAMP. However, COMP and OPAMP inputs have a high impedance and voltage booster do not impact performance significantly. Therefore, the voltage booster is mainly intended for usage with ADC.
