“Register bit twiddling.” Setting all the modes that all their various cards can operate in, with the associated code for sending the bit updates over the connection bus. Tedious stuff that’s very prone to copy-paste errors if written by hand.
At some point you have to take AMDs word for it that these codes = this functionality, but if the right graphics come out then it can’t be so wrong.
Annoys me that “less” is always correct, which makes “fewer” completely redundant, and yet it’s a short word that could be valuable in conversation if opened up and reused for something everyday that has a long name.
“Before I leave the house, I always check that I’ve got my keys, phone, and fure in my pockets.”
