10.5. ADC0 Analog Multiplexer
ADC0 on the C8051F700/2/4/6/8 and C8051F710/2/4/6 uses an analog input multiplexer to select the pos-
itive input to the ADC. Any of the following may be selected as the positive input: Port 0 or Port 1 I/O pins,
the on-chip temperature sensor, or the positive power supply (V
the ADC0MX register described in SFR Definition 10.9.
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 the corresponding bit in register PnMDIN to 0. To force the Crossbar to skip a Port pin, set the
corresponding bit in register PnSKIP to 1. See Section “28. Port Input/Output” on page 180 for more Port
I/O configuration details.
