2.2.8 A/D Trimmer
When testing the analog-to-digital convertor (ADC) peripheral, two trimmers must be connect-
ed to channels 6 and 7 of the ADC0. Make sure that the analog voltage never exceeds the
supply voltage. Two different jumpers must be used to connect analog inputs AD6 and AD7 to
the trimmer via connector TP17. Connector TP17 can also be used to connect analog inputs
AD6 and AD7 to any other external voltage source.
