9.0. Voltage Reference Source
The
EasydsPIC6
development system provides an MCP1541 circuit which generates the voltage reference used for A/D conversion.
The value of the voltage reference is 4.096V. This voltage is suppled to the microcontroller via the RB0 pin. For the RB0 pin to be fed
with the reference voltage, it is necessary to set switch 7 on the DIP switch SW9 to ON position.
