Functions

void XDptx_SetHpdEventHandler (XDptx *InstancePtr, XDptx_HpdEventHandler CallbackFunc, void *CallbackRef)

void XDptx_SetHpdPulseHandler (XDptx *InstancePtr, XDptx_HpdPulseHandler CallbackFunc, void *CallbackRef)

void XDptx_HpdInterruptHandler (XDptx *InstancePtr)

void XDptx_HpdInterruptHandler ( XDptx * InstancePtr )

This function is the interrupt handler for the XDptx driver.

When an interrupt happens, it first detects what kind of interrupt happened, then decides which callback function to invoke.

Parameters:

InstancePtr

is a pointer to the XDptx instance.

void XDptx_SetHpdEventHandler	(	XDptx *	InstancePtr,
		XDptx_HpdEventHandler	CallbackFunc,
		void *	CallbackRef
	)

This function installs a callback function for when a hot-plug-detect event interrupt occurs.

Parameters:

	InstancePtr	is a pointer to the XDptx instance.
	CallbackFunc	is the address to the callback function.
	CallbackRef	is the user data item that will be passed to the callback function when it is invoked.

void XDptx_SetHpdPulseHandler	(	XDptx *	InstancePtr,
		XDptx_HpdPulseHandler	CallbackFunc,
		void *	CallbackRef
	)

This function installs a callback function for when a hot-plug-detect pulse interrupt occurs.

Parameters:

	InstancePtr	is a pointer to the XDptx instance.
	CallbackFunc	is the address to the callback function.
	CallbackRef	is the user data item that will be passed to the callback function when it is invoked.
