9.5. ADC0 Analog Multiplexer (C8051T600/2/4 only)
ADC0 on the C8051T600/2/4 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 0 I/O pins, the on-chip temperature sensor, or
the positive power supply (V
SFR Definition 9.9.
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 XBR0 to ‘1’. See Section “22. Port Input/Output” on page 106 for more Port
I/O configuration details.
