Valid for internal clock mode only.
AVGON
Scans channel N and returns 4, 8, 12, or 16 results. Valid for repeat mode only.
Static power-down modes
Set to 0 to disable the instruction echo on DOUT.
Set to 1 to echo back the DIN instruction given at time = n onto the DOUT line at
time = n + 1. It takes 1 full cycle for the echoing to begin (Figure 8).
