The LEQ block implements the LEQ instruction. When the
rung conditions are true,the block verifies whether the value at source A is less than or
equal to the value at source B.
Controls the execution of the block. EnableIn reflects the
rung state preceding the block. If the rung state preceding the block is false,
EnableIn is false, the block does not execute and the outputs
are not updated.
If the EnableIn input to the block is false, the logic
implemented by the block is not executed and EnableOut signal is
set to false. If EnableIn is true, EnableOut
signal is set to true, if srcA is less than or equal to
srcb.
