1.6.3 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.
