Keep looking other solutions.

BR,

Well I have come to the realization that it is not the SHIFTOUT slowing me down but the pulsing of PORTA.3 for 4096 times. I need to get this to be faster.

For better help on this I am going to add on to an older post that deals with the chip I am using so I don't create multiples on here.

Thanks everyone for your help.
