Important note about ADC0 input configuration: Port pins selected as ADC0 inputs should be configured as
analog inputs, and should be skipped by the crossbar. To configure a Port pin for analog input, set to 0 the
corresponding bit in register PnMDIN and disable the digital driver (PnMDOUT = 0 and Port Latch = 1). To
force the crossbar to skip a Port pin, set to 1 the corresponding bit in register PnSKIP.
