Your Turn - Testing the New Program
There should be two ways to set the program mode. The first is to hold down the
pushbutton as you download the program. The other is to hold the pushbutton down as

mode, it's nonvolatile, meaning that disconnecting power or pressing and releasing Reset
cannot erase the value. You can also change the mode value by simply holding down the
pushbutton as you press and release Reset again.
You pretty much always have the choice of making the
EEPROM, or just having them reserve the space.
