QUESTION 13:
(Review:) How can a particular bit pattern be loaded into a register?
The bit pattern in $8 is moved to $9 ($8 is unchanged).
or $9,$8,$0 # $9 <-- contents of $8.
Copying the pattern in a source register to a destination register is called a move operation, even though the source register does not change.
or d,s,$0 # $d <-- contents of $s.
