N = 3, so the decoding object is the lower three bits in DX0, which are X2 ~ X0.
N = 3, so the decoding results need to be expressed by 2
When X2 = 1, X1 = 0, X0 = 1, the value it represents is 4 + 1 = 5, so M15 in the fifth place
from M10 changes to 1; when X2 ~ X0 is all zero, the value is 0, so M10 is 1 (M10 is the 0th
place).
If n = 0, the instruction will not be executed. If n is the value out of 0 ~ 16, the instruction
will not be executed.
When n = 16, if the decoding command
2 ^ 16 = 65536.
When the driver input is OFF, the instruction is not executed, and the decoding output of the
action is maintained.
