Explanation
1. This instruction compares the floating-point numbers in S and S
that in S , and then stores the results in D.
2
2. The value in S must be less than that in S
1
value during the execution of the FZCP instruction.
3. The operand D occupies three consecutive devices. The comparison results are stored in D, D+1, and D+2. If the
value in S is greater than the value in S, D is ON. If the value in S is between the value in S
1
D+1 is ON. If the compared value in S
Example
1.
If the operand D is M0, the comparison results are stored in M0, M1 and M2.
2.
When X0.0 is ON, the FZCP instruction is executed. M0, M1, or M2 is ON. When X0.0 is OFF, the FZCP instruction
is not executed, and the state of M0, the state of M1, and the state of M2 remain unchanged.
3.
If you want to clear the comparison result, use the RST or ZRST instruction.
