Weird Registers (Code Snippet)

Here is the behavior of the weird registers I mentioned on the main article. Note that it does it to those four registers in vic0 and vic1, keep that in mind so you don't think that there are 8 of these weird registers:

PS: This is from the S5L8720 SecureROM, in case you were wondering about the weird load address.
