When CIO 0.00 is ON in the following example, FIFO(633) reads the content of D4 (TB+4 for the stack
beginning at D0) and writes that data to D300.
After the data is written to D300, the stack pointer is decremented by one and the remaining data is
shifted down. (The content of D5 is shifted to D4 and the content of D6 is shifted to D5.)
