Be careful with the resistors connected to P13 and P14. Look carefully at the resistors
connected to P13 and P14 in Figure 6-11. There is gap between these two resistors. The
gap is shown because pin 8 on the 7-segment LED display is left unconnected. A resistor
connects I/O pin P13 to 7-segment LED display pin 9. Another resistor connects P14 to 7-
segment LED display pin 7.
