SAMPLEDLY
Configure sample delay. Sampling will occur after SAMPLEDLY+1 SAMPLECLK cycles.
EXTIME
Configure excitation time. Excitation will last EXTIME+1 EXCLK cycles.
Reserved
ALTEX
If set, alternative excite pin will be used for excitation
SAMPLECLK
EXCLK
EXMODE
GPIO mode for the excitation phase of the scan sequence. Note that DACOUT is only available on channels 0, 1, 2, 3, 12, 13, 14,
and 15.
