Status Register (ADSTAT)
This register provides the current status of the ADC module. RDYn bits are cleared by reading their
corresponding result (ADRSLTn) registers. The HLMTI and LLMTI bits are cleared by writing 1 to each
asserted bit in the ADC limit status (ADLSTAT) register. Likewise, the ZCI bit is cleared by writing 1 to
each asserted bit in the ADC zero crossing status (ADZCSTAT) register. The EOSIn bits are cleared by
writing 1 to them.
Except for CIP0 and CIP1 all bits in ADSTAT are sticky – after being set, they require some specific action
to be cleared. They are not cleared automatically on the next scan sequence.

Reserved, should be cleared.
7–0
DSn
Disable Sample bits. Setting or clearing DSn enables or disables the corresponding SAMPLEn field.
0 Enable SAMPLEn
1 Disable SAMPLEn and all subsequent samples. Which samples are actually disabled depends on the
conversion mode, sequential/parallel, and the value of SIMULT.
