Function Documentation

void HAL_SYSCFG_DisableIOAnalogSwitchBooster ( void   )

Disable the I/O analog switch voltage booster.

Return values:
None

Definition at line 638 of file stm32l4xx_hal.c.

void HAL_SYSCFG_DisableMemorySwappingBank ( void   )

Disable the Internal FLASH Bank Swapping.

Note:
This function can be used only for STM32L4xx devices.
The default state : Flash Bank1 mapped at 0x08000000 (and aliased @0x0000 0000) and Flash Bank2 mapped at 0x08100000 (and aliased at 0x00100000)
Return values:
None

Definition at line 534 of file stm32l4xx_hal.c.

void HAL_SYSCFG_DisableVREFBUF ( void   )

Disable the Internal Voltage Reference buffer (VREFBUF).

Return values:
None

Definition at line 617 of file stm32l4xx_hal.c.

void HAL_SYSCFG_EnableIOAnalogSwitchBooster ( void   )

Enable the I/O analog switch voltage booster.

Return values:
None

Definition at line 628 of file stm32l4xx_hal.c.

void HAL_SYSCFG_EnableMemorySwappingBank ( void   )

Enable the Internal FLASH Bank Swapping.

Note:
This function can be used only for STM32L4xx devices.
Flash Bank2 mapped at 0x08000000 (and aliased @0x00000000) and Flash Bank1 mapped at 0x08100000 (and aliased at 0x00100000)
Return values:
None

Definition at line 519 of file stm32l4xx_hal.c.

HAL_StatusTypeDef HAL_SYSCFG_EnableVREFBUF ( void   )

Enable the Internal Voltage Reference buffer (VREFBUF).

Return values:
HAL_OK/HAL_TIMEOUT

Definition at line 591 of file stm32l4xx_hal.c.

void HAL_SYSCFG_SRAM2Erase ( void   )

Start a hardware SRAM2 erase operation.

Note:
As long as SRAM2 is not erased the SRAM2ER bit will be set. This bit is automatically reset at the end of the SRAM2 erase operation.
Return values:
None

Definition at line 500 of file stm32l4xx_hal.c.

void HAL_SYSCFG_VREFBUF_HighImpedanceConfig ( uint32_t  Mode )

Configure the internal voltage reference buffer high impedance mode.

Parameters:
Mode,:specifies the high impedance mode This parameter can be one of the following values:

  • SYSCFG_VREFBUF_HIGH_IMPEDANCE_DISABLE: VREF+ pin is internally connect to VREFINT output.
  • SYSCFG_VREFBUF_HIGH_IMPEDANCE_ENABLE: VREF+ pin is high impedance.
Return values:
None

Definition at line 567 of file stm32l4xx_hal.c.

void HAL_SYSCFG_VREFBUF_TrimmingConfig ( uint32_t  TrimmingValue )

Tune the Internal Voltage Reference buffer (VREFBUF).

Return values:
None

Definition at line 579 of file stm32l4xx_hal.c.

void HAL_SYSCFG_VREFBUF_VoltageScalingConfig ( uint32_t  VoltageScaling )

Configure the internal voltage reference buffer voltage scale.

Parameters:
VoltageScaling,:specifies the output voltage to achieve This parameter can be one of the following values:

  • SYSCFG_VREFBUF_VOLTAGE_SCALE0: VREF_OUT1 around 2.048 V. This requires VDDA equal to or higher than 2.4 V.
  • SYSCFG_VREFBUF_VOLTAGE_SCALE1: VREF_OUT1 around 2.5 V. This requires VDDA equal to or higher than 2.8 V.
Return values:
None

Definition at line 551 of file stm32l4xx_hal.c.
