John: There're 3 articles below. They're about "the chosen clock line". I guess you're better read them first.

Me: OK.

John: After you read the 3 articles above, we may start now. 

Me: OK.

John: Now, look at the picture above. There is a register called register_power_source_chosen.

Me: OK.

John: If you're not sure what register is, you may read this article (https://wodewangzhishime.blogspot.com/2021/07/httpswodewangzhishime_94.html) first.

Me: OK. I've read it.

John: I assume that power source 1 is "Battery" and power source 2 is AC to DC rectifier.

Me: OK.

John: This is the principles of hacking (https://wodewangzhishime.blogspot.com/2022/06/httpswodewangzhishime_13.html).

Me: I assume the binary of battery is 011 and the binary of AC to DC rectifier is 010.

John: OK.

Me: Hackers change 011 to 010. That mean hackers change the power source from AC to DC rectifier to "Battery".

John: Correct. That mean hackers change the chosen line of power source.

Me: Look at the followings.
