WebMar 17, 2014 · C8051F560 DJNZ. When testing the C8051F560 with DJNZ in a timing loop I find that the DJNZ R5,$ gives a delay of 4 cycles (3 when R5 = 0), rather than the delay of 3 cycles in the data sheet. The machine code for the DJNZ here is DDh so it is the register version. Testing the direct version gave DJNZ (machine code FDh) as 5 cycles rather … WebOthers prefer a more traditional approach and use a full stop (which indicates that the rest of the word is missing). You can use either style, but the important thing is to be consistent. If the full form starts with a capital letter, then the shortening must start with a capital letter (Monday → Mon., approximately → approx.) Pronunciation
