6.1. ADC0 Analog Multiplexer
ADC0 includes an analog multiplexer to enable multiple analog input sources. Any of the following may be
selected as an input: P0.0–P3.0, the on-chip temperature sensor, the core power supply (V
(GND). ADC0 is single-ended and all signals measured are with respect to GND. The ADC0 input
channels are selected using the ADC0MX register as described in SFR Definition 6.3.
Important Note About ADC0 Input Configuration: Port pins selected as ADC0 inputs should be config-
ured as analog inputs, and should be skipped by the Digital Crossbar. To configure a Port pin for analog
input, set to 0 the corresponding bit in register PnMDIN. To force the Crossbar to skip a Port pin, set to 1
the corresponding bit in register PnSKIP. See Section “18. Port Input/Output” on page 147 for more Port
I/O configuration details.
