Function Documentation

void HAL_SYSCFG_DisableIOAnalogSwitchBooster

(

void

)

Disable the I/O analog switch voltage booster.

Return values:

None

Definition at line 744 of file stm32l4xx_hal.c.

void HAL_SYSCFG_DisableMemorySwappingBank

(

void

)

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 640 of file stm32l4xx_hal.c.

void HAL_SYSCFG_DisableVREFBUF

(

void

)

Disable the Internal Voltage Reference buffer (VREFBUF).

Return values:

None

Definition at line 723 of file stm32l4xx_hal.c.

void HAL_SYSCFG_EnableIOAnalogSwitchBooster

(

void

)

Enable the I/O analog switch voltage booster.

Return values:

None

Definition at line 734 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 625 of file stm32l4xx_hal.c.

References FB_MODE_BB.

HAL_StatusTypeDef HAL_SYSCFG_EnableVREFBUF

(

void

)

Enable the Internal Voltage Reference buffer (VREFBUF).

Return values:

HAL_OK/HAL_TIMEOUT

Definition at line 697 of file stm32l4xx_hal.c.

References HAL_GetTick(), and VREFBUF_TIMEOUT_VALUE.

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

References SCSR_SRAM2ER_BB.

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 673 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 685 of file stm32l4xx_hal.c.

References assert_param, and IS_SYSCFG_VREFBUF_TRIMMING.

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_OUT2 around 2.5 V. This requires VDDA equal to or higher than 2.8 V.

Return values:

None
