TMS320F28335: In DSP28335, can it support the function pointer?

Part Number: TMS320F28335

I have been using Embedded user graphical interface (uC/GUI) recently, but there are some problems. When the program executes to the code GUI_pLCD_APIList->pfDrawBitmap(x0, y0, xsize, ysize, xMul, yMul, BitsPerPixel, BytesPerLine, pPixel, pTrans), it jumps directly to the unreasonable interrupt code ILLEGAL_ISR(void) and cannot jump to the corresponding function.Why is it happening? In DSP28335, can it support the function pointer?
