The following diagram shows the scan-by-scan results of the execution for our example
program. The table counter is set to 2 initially, and it will automatically increment from 2 to 6
as the instruction is executed. Notice how SP56 comes on when the table counter is 6, which
is equal to the table length. Plus, although our example does not show it, we are assuming that
there is another part of the program that changes the value in V1500 (data source) prior to the
execution of the ATT instruction.
