Only switch to OP when processdata from bus seen (Certification)

TF 1200 Testcases from OP to Any (CTT V2.1.0.0)

Background Conformance Test and slave in Freerun Mode:

Watchdog ist started in testcase and in following testcase still running. Slave than is switched to SafeOP and LRW/LW command is send. When the handshake trigger from host comes in time, slave triggers the wdg. again, all O.K.. But when the handshake comes directly before the LRW/LW command from testcase, the wgd. is not triggered because LRW/LW seen is a requirement to allow wdg. triggering. The wdg. expires until the next handshake e.g. 10ms later comes. Appliactions which constantly update the DPM faster than 9 ms may not run into the problem (to be tested). (For detailed timing picture see linked issue "fehler 14082008.png".)

Solution:

• Only Switch to OP when handshake and processdata from master seen or no handshake and processdata from master seen.
• Ignore wdg. event when not in OP (linked Issue)
