12.3 Functional Description
The Stellaris ADC collects sample data by using a programmable sequence-based approach instead
of the traditional single or double-sampling approaches found on many ADC modules. Each sample
sequence is a fully programmed series of consecutive (back-to-back) samples, allowing the ADC
to collect data from multiple input sources without having to be re-configured or serviced by the
processor. The programming of each sample in the sample sequence includes parameters such as
the input source and mode (differential versus single-ended input), interrupt generation on sample
completion, and the indicator for the last sample in the sequence. In addition, the μDMA can be
used to more efficiently move data from the sample sequencers without CPU intervention.
12.3.1 Sample Sequencers
The sampling control and data capture is handled by the sample sequencers. All of the sequencers
are identical in implementation except for the number of samples that can be captured and the depth
of the FIFO. Table 12-3 on page 537 shows the maximum number of samples that each sequencer
can capture and its corresponding FIFO depth. Each sample that is captured is stored in the FIFO.
In this implementation, each FIFO entry is a 32-bit word, with the lower 12 bits containing the
conversion result.

For a given sample sequence, each sample is defined by bit fields in the ADC Sample Sequence
Input Multiplexer Select (ADCSSMUXn) and ADC Sample Sequence Control (ADCSSCTLn)
registers, where "n" corresponds to the sequence number. The ADCSSMUXn fields select the input
pin, while the ADCSSCTLn fields contain the sample control bits corresponding to parameters such
as temperature sensor selection, interrupt enable, end of sequence, and differential input mode.
Sample sequencers are enabled by setting the respective ASENn bit in the ADC Active Sample
Sequencer (ADCACTSS) register and should be configured before being enabled. Sampling is
then initiated by setting the SSn bit in the ADC Processor Sample Sequence Initiate (ADCPSSI)
register. In addition, sample sequences may be initiated on multiple ADC modules simultaneously
using the GSYNC and SYNCWAITbits in the ADCPSSI register during the configuration of each ADC
module. For more information on using these bits, refer to page 576.
When configuring a sample sequence, multiple uses of the same input pin within the same sequence
are allowed. In the ADCSSCTLn register, the IEn bits can be set for any combination of samples,
allowing interrupts to be generated after every sample in the sequence if necessary. Also, the END
bit can be set at any point within a sample sequence. For example, if Sequencer 0 is used, the END
bit can be set in the nibble associated with the fifth sample, allowing Sequencer 0 to complete
execution of the sample sequence after the fifth sample.
After a sample sequence completes execution, the result data can be retrieved from the ADC
Sample Sequence Result FIFO (ADCSSFIFOn) registers. The FIFOs are simple circular buffers
that read a single address to "pop" result data. For software debug purposes, the positions of the
FIFO head and tail pointers are visible in the ADC Sample Sequence FIFO Status (ADCSSFSTATn)
registers along with FULL and EMPTY status flags. If a write is attempted when the FIFO is full, the
write does not occur and an overflow condition is indicated. Overflow and underflow conditions are
monitored using the ADCOSTAT and ADCUSTAT registers.
