① NCU1, channel1: Enable issued using the AXCTSWE command
② NCU2, channel2: Enable issued using the AXCTSWE command
③ NCU1, channel2: Enable issued via AXCTSWE command → all enables of all channels are now
present in the NCU1 → the overall enable status of NCU1 is transferred to NCU2 via link
communication
④ NCU2, channel1: Enable issued via AXCTSWE command → all enables of all channels are now
present in the NCU2 → the overall enable status of NCU2 is transferred to NCU1 via link
communication
All enable signals for all channels (NCU2 and NCU1) are now present in NCU2 → the axis
container rotation is performed in NCU2
⑤ NCU1: All enable signals for all channels (NCU1 and NCU2) are now present in NCU1 → the
axis container rotation is performed in NCU1
⑥ NCU1/NCU2: axis container rotation has been completed
Figure 2-19 Cross-NCU enable and axis container rotation
