### Notes

The instructions must be run at privilege level 0 or in real-address mode; otherwise, a protection exception will be raised.

The reg field within the ModR/M byte specifies which of the special registers in each category is involved. The two bits in the mod field are always 11. The r/m field specifies the general register involved.

Always set undefined or reserved bits to the value previously read.
