Mitsubishi plc programming Bit component transfer

With the transfer instruction,
For example, MOV k1x0 k1y0, k1 represents 4 bits (x0–x3), k2 is 8 bits (xo–x7), k3 is 12 bits, k4 is 16 bits, and x and y are the same.

For example, x3–x0 is 1001, and y 3 — y0 are 1, 0, 0, and 1, respectively. The same principle
