Function Documentation

void SYSCFG_CompensationCellCmd

(

FunctionalState

NewState

)

Enables or disables the I/O Compensation Cell.

Note:

The I/O compensation cell can be used only when the device supply voltage ranges from 2.4 to 3.6 V.

Parameters:

NewState,:

new state of the I/O Compensation Cell. This parameter can be one of the following values: ENABLE: I/O compensation cell enabled DISABLE: I/O compensation cell power-down mode

Return values:

None

void SYSCFG_DeInit

(

void

)

Deinitializes the Alternate Functions (remap and EXTI configuration) registers to their default reset values.

Parameters:

None

Return values:

None

void SYSCFG_ETH_MediaInterfaceConfig

(

uint32_t

SYSCFG_ETH_MediaInterface

)

Selects the ETHERNET media interface.

Parameters:

SYSCFG_ETH_MediaInterface,:

specifies the Media Interface mode. This parameter can be one of the following values: SYSCFG_ETH_MediaInterface_MII: MII mode selected SYSCFG_ETH_MediaInterface_RMII: RMII mode selected

Return values:

None

void SYSCFG_EXTILineConfig	(	uint8_t	EXTI_PortSourceGPIOx,
		uint8_t	EXTI_PinSourcex
	)

Selects the GPIO pin used as EXTI Line.

Parameters:

	EXTI_PortSourceGPIOx	: selects the GPIO port to be used as source for EXTI lines where x can be (A..I).
	EXTI_PinSourcex,:	specifies the EXTI line to be configured. This parameter can be EXTI_PinSourcex where x can be (0..15, except for EXTI_PortSourceGPIOI x can be (0..11).

Return values:

None

FlagStatus SYSCFG_GetCompensationCellStatus

(

void

)

Checks whether the I/O Compensation Cell ready flag is set or not.

Parameters:

None

Return values:

The

new state of the I/O Compensation Cell ready flag (SET or RESET)

void SYSCFG_MemoryRemapConfig

(

uint8_t

SYSCFG_MemoryRemap

)

Changes the mapping of the specified pin.

Parameters:

SYSCFG_Memory,:

selects the memory remapping. This parameter can be one of the following values: SYSCFG_MemoryRemap_Flash: Main Flash memory mapped at 0x00000000 SYSCFG_MemoryRemap_SystemFlash: System Flash memory mapped at 0x00000000 SYSCFG_MemoryRemap_FSMC: FSMC (Bank1 (NOR/PSRAM 1 and 2) mapped at 0x00000000 SYSCFG_MemoryRemap_SRAM: Embedded SRAM (112kB) mapped at 0x00000000

Return values:

None
