I'm taking a look at the Intel developers guide and there is a notation there that I didn't understand.

Since there are several guys with more experience here, probably someone can help me. This is the table with the default values of the registers after a system reset, from Intel Developers Guide, page 2285.

That does the "H2" means at the attached picture ?

And what toes the xxH3 means too ?

Thanks and Regards
