21.2.1 General Information
The Status Register is (if enabled) located at 0x000–0x001 and constitutes a bit-field as follows:
Note: Internally, this is treated as a Motorola-format word (i.e. MSB first). If the higher level network
uses a different byte order, the upper and lower bytes will appear swapped.
21.2.2 Status Codes in Master Mode and DF1 Master Mode
(This table is valid only in Master Mode and DF1 Master Mode).
Note: Conditions of type “Error” will eventually be followed by a “No Error” condition when the cause
has been resolved. Conditions of type “Warning” are however considered informational and may not
necessarily be followed by a “No Error” condition later on.
