EXTI_TLISensitivity_TypeDef EXTI_GetTLISensitivity

(

void

)

Get the TLI interrupt sensitivity.

Parameters:

None

Return values:

EXTI_TLISensitivity_TypeDef

The TLI interrupt sensitivity read.

void EXTI_SetExtIntSensitivity	(	EXTI_Port_TypeDef	Port,
		EXTI_Sensitivity_TypeDef	SensitivityValue
	)

Set the external interrupt sensitivity of the selected port.

Warning:

• The modification of external interrupt sensitivity is only possible when the interrupts are disabled.
• The normal behavior is to disable the interrupts before calling this function, and re-enable them after.

Parameters:

Port	The port number to access.
SensitivityValue	The external interrupt sensitivity value to set.

Return values:

None

Required preconditions:

Global interrupts must be disabled before calling this function.

void EXTI_SetTLISensitivity

(

EXTI_TLISensitivity_TypeDef

SensitivityValue

)

Set the TLI interrupt sensitivity.

Parameters:

SensitivityValue

The TLI interrupt sensitivity value.

Return values:

None

Required preconditions:

Global interrupts must be disabled before calling this function.
