Command Interface

General Structure of the Command Buffer

Depending on the command, the command buffer can extend over a maximum of 14 banks (bank 2±15 in the analog module) with a maximum of 224 bytes.

In the following description of the command interface, the start address 0 is assumed for the analog input module of the CP to simplify byte numbering.
