Registers are 0-based and use the Unit 0 addresses of the document, which cover every section of the device. Multi-register values (32-bit counters, serial number, floats) are read here with the most significant register first, as the document states.
Reserved, obsolete and internal registers, and registers reachable only through a section unit (Unit 1 to 3), are left out.
