Ancyker 6733c9f57c Add note to self-test on HW3 that the EEP switch should be set to on. 
Unable to actually test this myself because I do not have a HW3 to test on. However, looking at the schematic, if the EEP switch is set to the off position then the pin will be floating and the result of the 1K resistor test will be random.
