Your question is Bit Manipulation in ECU Debug. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe a time you used bit manipulation while working on ECU bring-up or debugging.
Explain the register or protocol problem, how you identified the relevant bits, and how you avoided changing unrelated state. Include the tools you used, such as a debugger, logic analyzer, CANoe, or Lauterbach TRACE32, and describe how you verified the fix.
