In this exercise, you enter a timer instruction with a time delay of 10 seconds.

Two different types of timer status bits activate output pilot lights #0 and #1.

The first type, called a “timer timing” status bit turns on output #0 for 10

seconds. The second type, called a “done” status bit, turns on output #1 after

10 seconds.

The program that you will enter in this exercise will look like the one in the
