The AVR port pins PE7 and PE6 are used to sense the hardware revision of the
DB101, or rather what type of display that assumed mounted on the DB101. The
resistors R123 and R124 are either left open or closed using 100 ohm resistors. Table
2-2 shows resistor configurations and the assumed displays.
