| For example, to turn on only the right two digits of the eight digit display, AN1 and AN0 must have a logic value of **0** and the other anode signals must have a logic value of **1**. | For example, to turn on only the right two digits of the eight digit display, AN1 and AN0 must have a logic value of **0** and the other anode signals must have a logic value of **1**. | ||
| - | In the following example, two of the digits are turned on by setting their corresponding anode to zero. All of the other digits are off since their anode signals are set to one. In addition, the digit **3** is displayed based on which cathode signals have a logic **1**. The digit point is also on since the cathode signal, DP, associated with the digit point is set to **0**. | + | In the following example, two of the digits are turned on by setting their corresponding anode to zero.
