SVC blocked at Bus Synchronous Mode with reduced round-trip time

The SVC (and RT Data handling) could not called in CP3 if the Slave is configured to "Bus Synchronous Mode with reduced round-trip time". If this get configured and the master configures MDT/AT/NRT and the Transmission Starting time is equal to t5 of the slave. In this case the slave calculates the TXBuffer Interrupt to the same point as the MST's are received. If MSTs and TXBuffer Interrupt are equal, the Timer is called too late. The slave has to start processing the TXBuffer Date before MSTs are recieved.
