Detailed Description

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_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..K) for STM32F42xxx/43xxx devices, (A..I) for STM32F405xx/407xx and STM32F415xx/417xx devices or (A, B, C, D and H) for STM32401xx devices.
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) for STM32F405xx/407xx and STM32F405xx/407xx devices and for EXTI_PortSourceGPIOK x can be (0..7) for STM32F42xxx/43xxx devices.

Return values

None
