RW 7'h0 CDI - Calibration Data Input
(CDI)
when the ADC command is a load
calibration command, this bit field
defines the digital offset calibration
data to be loaded.

RW 2'h0 Resolution (Resolution)
This bit field defines the number of
bits of precision. It is defined
thusly:
0 - 6bits
1 - 8bits
2 - 10bits
3 - 12bits
13:9 RW 5'h0 CSTI - Channel Sequence Table
Index (CSTI)
when the ADC command is a start
conversion command, this bit field
defines the first entry in the channel
sequence table to be sampled.
If repeated or continuous
conversions are commanded,
subsequent conversions will follow
the channel sequence table
8:4 RW 5'h0 NS - Number of Samples (NS)
when the ADC command is start
single conversion, this bit field
defines the number of repeated
conversions before stopping.
When the ADC command is start
continuous conversions, this bit
field defines the number of
conversion between interrupts.
This bit field is ignored otherwise. It
encoded thusly:
numConversions=NS+1
3 RW 1'h0 IE - Interrupt Enable (IE)
when set, this bit enables an
interrupt on completion of the ADC
operation.
2:0 RW 3'h0 ADC Command (ADC_Command)
this bit field defines ADC operation.
It is encoded thusly:
0 = Start single conversion
1 = Start continuous conversion
2 = Reset calibration
3 = Start calibration
