5.1.2 Device Configuration
This sheet is used to specify the Global controls for the AFE. This includes the specification of whether the
LDO is enabled or not as well as the mode of clocking (External clock mode using a free-running clock on the
clock input, internal oscillator mode, or Single-shot mode using a Pulse train on the clock input). Fill the rows
in sequence from top to bottom. Fill only the parameters that show up in the Blue boxes. Manually fill each cell
using the drop down boxes (do not cut and paste values across cells). Do not modify the cream-colored boxes.
The light green boxes can be either left blank (to use the default values) or can be filled.
