14.2 Status Register Contents (Gateway to Control
System)

14.2.1 General Information

The Status Register is (if enabled) located at 0x000–0x001 and constitutes a bit-field as follows:
bit(s) Name
15 Send
(SR_HS_SEND)
14 Confirm
(SR_HS_CONFIRM)
13 Data Valid
(Master Mode and DF1
Master Mode Only)
12... 8 Status Code
7... 0 Data
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.

necessarily be followed by a "No Error" condition later on.
