I have on my board two PISO shift registers in series, giving an output train of 16 bits. The problem is that the order of the bits is reversed compared to what I need. That means, the last input of the second PISO shift register is the first of my serial train (as usual), while I need it to be the last one. I cannot change my PCB and I cannot find any PISO-FIFO (sort of) component able to do what I need.
Do you have any idea? Thanks
