LM3S5D56 Datasheet, PDF (602/1146 Pages) Texas Instruments – Stellaris® LM3S5D56 Microcontroller

Analog-to-Digital Converter (ADC)
Register 32: ADC Sample Sequence 1 Digital Comparator Select (ADCSSDC1),
offset 0x074
Register 33: ADC Sample Sequence 2 Digital Comparator Select (ADCSSDC2),
offset 0x094
These registers determine which digital comparator receives the sample from the given conversion
on Sample Sequence n if the corresponding SnDCOP bit in the ADCSSOPn register is set. The
ADCSSDC1 register controls the selection for Sample Sequencer 1 and the ADCSSDC2 register
controls the selection for Sample Sequencer 2.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Sample 3 Digital Comparator Select
When the S3DCOP bit in the ADCSSOPn register is set, this field
indicates which digital comparator unit (and its associated set of control
registers) receives the eighth sample from Sample Sequencer n.
Note: Values not listed are reserved.
Value Description
0x0 Digital Comparator Unit 0 (ADCDCCMP0 and ADCCCTL0)
0x1 Digital Comparator Unit 1 (ADCDCCMP1 and ADCCCTL1)
0x2 Digital Comparator Unit 2 (ADCDCCMP2 and ADCCCTL2)
0x3 Digital Comparator Unit 3 (ADCDCCMP3 and ADCCCTL3)
