EX is independent of the format of the target instruction. You can EX
anything (except EX). It just plugs that second byte of the target
instruction. You can EX an LR and vary which registers get copied.
ZAP has L1/L2 so you want to load your EX register with (L1 * 16) + L2
(where L1 and L2 are base 0,
What?
and a shift might be a better choice than an
actual multiply).
Shift is always better than multiply.
