C8051F330/1/2/3/4/5
measured from ‘0’ to VREF x 1023/1024. Example codes are shown below for both right-justified and left-
justified data. Unused bits in the ADC0H and ADC0L registers are set to ‘0’.
When in Differential Mode, conversion codes are represented as 10-bit signed 2’s complement numbers.
Inputs are measured from –VREF to VREF x 511/512. Example codes are shown below for both right-jus-
tified and left-justified data. For right-justified data, the unused MSBs of ADC0H are a sign-extension of the
data word. For left-justified data, the unused LSBs in the ADC0L register are set to ‘0’.
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 (for n = 0,1). To force the Crossbar to skip a Port
pin, set to ‘1’ the corresponding bit in register PnSKIP (for n = 0,1). See
on page 123

The typical temperature sensor transfer function is shown in Figure 5.2. The output voltage (V
positive ADC input when the temperature sensor is selected by bits AMX0P4–0 in register AMX0P.
