During programming, the MCU needs to be put in a Special Bootstrap Mode so that the program can be loaded in via the serial port. This position is labelled LOAD on the RUN/LOAD switch (SW2). The other switch (SW3) is for protecting the contents of EEPROM from corruption due to power glitches. During programming, slide the switch to the LOAD position. After the code has been loaded, slide both switches away from the LOAD position (ie. to RUN and PROT). Reset the board to cause the MCU to begin executing your program.
