I have read the s5 115 U refference guide document, there was mentioned that "Do DW" function is :Process data word. The next operation is combined through logic OR with the parameter specified in the dataword and executed. i cannot understand how the instruction work, so would you mind to explain me more about this "Do Dw ** " instruction ? C DB 21 do dw 222 L dw 0 L dw 224 -F T Dw 225 thank you for your attention and help
