Repeat Bit Operands
The MOV (move) instruction moves 16-bit data. When a bit operand such as input, output, internal relay, or shift register is
designated as the source or destination operand, 16 bits starting with the one designated by S1 or D1 are the target data. If
a repeat operation is designated for a bit operand, the target data increases in 16-bit increments.
Overlapped Operands by Repeat
If the repeat operation is designated for both the source and destination and if a portion of the source and destination areas
overlap each other, then the source data in the overlapped area is also changed.
