voltage to AVREFH pin of CON1 to provide user define ADC high
reference voltage.
AVREFL/VSS
: AVREFL s the ADC low reference voltage. Short this jumper will connect
the AVREFL to VSS. Remove this jumper and connect external reference
voltage to AVREFL pin of CON1 to provide user define ADC low reference
voltage..

6.4 CON1 and JP6: IO Port interface Circuit Schematic
Figure 6-3 CON1: Generic IO Port
Figure 6-4 JP6: IO Expansion Port
Figure 6-5 listed the Generic IO port (CON1) pin assignment. All the IO action could be measured from
this port. The JP6 is IO expansion port reserved for future usage.
When the SN8ICE 2K connect to Easy Writer, these two jumpers,
AVREFH/VDD and AVREFL/VSS should be shorted
