Available Internal Data

See Appendix A – I/O Signal Descriptions for
additional details regarding each input/output.
Unless stated otherwise,

Bytes are stored in each instance in little endian
order. (byte order within instance: least
significant...most significant)

Values are subject to the same maximum and
minimum restrictions of the ADM.
