It is also [to],[from] in the cpu itself on motorola cpus like the 68000. It
is quite
logical to have it like this because the from can be a number or a direct
adress in memory, which has to be stored behind the instruction. But even if
it is a move between registers, the to and from fields in the instruction
are ordered in that way.
