Figure 18. ADC Interface Registers
To perform an A/D conversion, one must set the input attenuator and channel selector. Two input ranges may be
set using the attenuator, 0 - 2.048V and 0 - 6.144V. Table 8 shows the input attenuator settings.
Table 8. ADC Input Attenuator Control
The input selector may be set to monitor any one of the ten VMO
N
inputs, the VCCA input, or the VCCI
N
P input.
Table 9 shows the codes associated with each input selection.
Table 9. V
MON
Address Selection Table
Writing a value to the ADC_MUX register to set the input attenuator and selector will automatically initiate a conver-
sion. When the conversion is in process, the DO
N
E bit (ADC_VALUE_LOW.0) will be reset to 0. When the conver-
sion is complete, this bit will be set to 1. When the conversion is complete, the result may be read out of the ADC by
performing two I
2
C read operations; one for ADC_VALUE_LOW, and one for ADC_VALUE_HIGH. It is recom-
mended that the I
2
C master load a second conversion command only after the completion of the current conversion
