Block BTR and BTR_FD during operation
CAN FD ISO standard says that bus timing parameters must be protected from being changed when CAN bus communication is ongoing...
So far we can write to BTR and BTR_FD at any time. IP-xact generator can be extended by more "lock" signals. Right now single lock signal is used. Lock signal can be specified as value in Vendor Extensions of IP-XACT.
This-way write to BTR and BTR_FD will be gated by value of SETTTINGS[ENA]
