NI 9205/9206 Scan List
The scan list channel codes consist of eight bit fields in a 32-bit entry.
Bits 23..16 describe the data offset to store a conversion at time t, and
bits 15..0 describe a complex conversion control code that takes effect
two conversions in the future, at time t+2. On the NI 9205/9206, this
conversion code is listed in Table 16.
