8.5. ADC0 Analog Multiplexer (C8051T610/1/2/3/6 only)
ADC0 on the C8051T610/1/2/3/6 uses an analog input multiplexer to select the positive input to the ADC.
Any of the following may be selected as the positive input: Port 1, 2 and 3 I/O pins, the on-chip temperature
sensor, or the positive power supply (V
described in SFR Definition 8.9.
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 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 “21. Port Input/Output” on page 113 for more Port
I/O configuration details.
Note: Not all pins exist on all
packages. See the AMX0P
selection table for details on
which pins are available for
selection.
