Explanation
1. This instruction checks the state of the n
2. The operand n used in the 16-bit instruction must be between 0–15. For 32-bit instructions, n must be between 0–
31.
3. Only the 32-bit instructions can use the 32-bit counter, but not the device E.
Example
1.
When X0.0 is ON, Y0.1 is ON if the value of the 15
th
the 15 bit in D0 is 0.
2.
When X0.0 switches to OFF, the state of Y0.1 remains the same as before X0.0 switches to OFF.
