Analog-to-Digital Converter (ADC)
Register 31: ADC Sample Sequence 1 Operation (ADCSSOP1), offset 0x070
Register 32: ADC Sample Sequence 2 Operation (ADCSSOP2), offset 0x090
This register determines whether the sample from the given conversion on Sample Sequence n is
saved in the Sample Sequence n FIFO or sent to the digital comparator unit. The ADCSSOP1
register controls Sample Sequencer 1 and the ADCSSOP2 register controls Sample Sequencer 2.

Reset Description
0x0000.0
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 Operation
Value Description
0 The fourth sample is saved in Sample Sequence FIFOn.
1 The fourth sample is sent to the digital comparator unit specified
by the S3DCSEL bit in the ADCSSDC0n register, and the value
is not written to the FIFO.
