Purpose of this resistor in Arduino Nano schematic I was looking at the Arduino Nano's schematic and noticed a resistor that seems to be pointless (RP2C on this picture).

Also there is numbers 6 and 3 on it, does it mean that resistor is connected to pins 6 and 3 on FT232 or to the same pins on Atmega328?
The resistor is one of 4 resistors that make up an SMD resistor array, RP2. It is seen on the board here:


The resistor array works like this:
  

The resistor on this array is spare, so both terminals are grounded.
