Clear a long in memory.
Clear a word in memory.
Clear a register. Clear an entire accumulator when FF
specified; clear an entire AGU register when Rn is
specified.
Note: When clearing an AGU register, it is
recommended to use
beneficial because it clears the register without
introducing any dependencies due to the pipeline.
Not permitted for the 32-bit Y register—instead use
MOVE.W #0,Y
.
