• Digit specification in bit device

For the 16-bit operation instruction, specify K1 to K4. For the 32-bit operation instruction, specify K1 to K8.

• Note that the 32-bit values [m1+1, 1], [m2+1, m2] and [n+1, n] are valid when D or R is specified as "m1", "m2" or

"n" in a 32-bit instruction.

In the case of "DFROM D0 D2 D100 R0", "m1" is [D1, D0], "m2" is [D3, D2], and "n" is [R1, R0].
