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 … Webarrow_forward. Design an open loop comparator to provide the following logic: Vo = 13 V for Vi > 7.5 VVo = -13 V for Vi < 7.5 VVsat = +/- 15V. arrow_forward. Create a CE circuit with a voltage gain of 5 and a 500 ohm output impedance. Assume RE has a 300 mV voltage drop and R1 has a current ten times the base current. arrow_forward.

WebDJNZ R7, LOOP_1_MILLI takes 2 instruction cycle to execute Total instruction cycles = 4 So, it takes 4 instruction cycles, or 4 µsecs, to execute the loop. Thus, if we execute the loop 250 times it will take a 1000 µsecs (250 x 4), i.e. 1 millisecond, to complete the loops. Figure 3.1 ONE_MILLI_SUB flow chart http://bhumish.weebly.com/mpmc-programs.html
WebLooking at the fast loop however, the inner loop uses only a DJNZ instruction which takes 14 T-states, just like a normal 8-bit loop. Once every 256 iterations it also executes the outer loop which takes a little longer but still less than the common loop: 25 T-states.
