The following diagram shows the scan-by-scan results of the execution for our example
program. In our example, we show the table counter set to 4, initially. (Remember, you can
set the table counter to any value that is within the range of the table.) The table counter
automatically decrements from 4 to 0 as the instruction is executed. Notice how the last two
table positions, 5 and 6, are not moved up through the table. Also, notice that SP56, which
comes on when the table counter is zero, is only on until the end of the scan.
