   |------------------------------------------------------------|
   |   Note:This toggle functions as a clearing of the firmware |
   |   on the board. If the jumper is first on Pins 2 & 3 then  |
   |   changing this jumper to Pins 1 & 2 will cause the        |
   |   firmware to be erased and default values to be loaded.   |
   |   This will then stay until the jumper is moved again.     |
