(2) Examples of Queries/Responses
Queries are implemented by changing (writing) a 1-word register and thus the basic pattern is the same with all queries.
The only differences are the starting address and data. The following explanations use axis (0) or axis (12) in the
example.
[1] Write gateway control signals 0, 1
MON (bit 15 of control signal 0) is the only applicable control signal. Always turn this signal ON to enable the
applicable control.
