void XVTpg_InterruptHandler

(

XV_tpg *

InstancePtr

)

This function is the interrupt handler for the TPG core driver.

This handler clears the pending interrupt and determined if the source is frame done signal. If yes, starts the next frame processing and calls the registered callback function

The application is responsible for connecting this function to the interrupt system. Application beyond this driver is also responsible for providing callbacks to handle interrupts and installing the callbacks using XVTpg_SetCallback() during initialization phase.

Parameters

InstancePtr

is a pointer to the core instance that just interrupted.

Returns

None.

Note

None.

void XVTpg_SetCallback	(	XV_tpg *	InstancePtr,
		u32	HandlerType,
		void *	CallbackFunc,
		void *	CallbackRef
	)

Install an asynchronous callback function for interrupt handling.

This function installs an asynchronous callback function for the given HandlerType:

HandlerType                     Callback Function Type



(XVTPG_HANDLER_DONE)       DoneCallback
(XVTPG_HANDLER_READY)      ReadyCallback

Parameters

  

    
InstancePtr
is a pointer to the tpg IP instance.

    
HandlerType
is the type of handler to be installed (DONE or READY).

    
CallbackFunc
is the address of the callback function.

    
CallbackRef
is a user data item that will be passed to the
      callback function when it is invoked.
  
  

Returns
None
Note
Invoking this function for a handler that already has been
      installed replaces it with the new handler.
