SMPL_SET 15:11 — Set to 10110 to select the SampleSet register.
SEQ_LENGTH 10:3 00000000
8-bit binary word indicating desired sequence length. The equation is:
Sequence length = SEQ_LENGTH + 1
00000000 = Sequence length = 1
11111111 = Sequence length = 256
Coding: Straight binary
Maximum length: 256 ADC conversions
— 2:0 — Unused.
