6.3 MOVE BITS Instruction (MOVB)
[Outline]
The MOVB instruction moves the designated number of bits (Width) from the beginning of the move
source bits (Source) to the beginning of the move destination bits (Dest). The move process is
performed one bit at a time in the direction in which the relay number increases.
Unless the move source bits overlap with the move destination bits, the move source bit table is stored.
If there is overlap between them, the move source bit table may not be stored.
