The general configuration of the three nodes is identical, there are differences in the Operation
Mode, the TT Matrix Limits, the Message RAM, and the Trigger Memory. Note that the CPU
has to wait after each write access to the IF1 Command Request Register for the requested
transfer to be completed (check of Busy bit).
