WebDescription: DA adjusts the contents of the Accumulator to correspond to a BCD (Binary Coded Decimal) number after two BCD numbers have been added by the ADD or ADDC instruction. If the carry bit is set or if the value of bits 0-3 exceed 9, 0x06 is added to the accumulator. If the carry bit was set when the instruction began, or if 0x06 was added to … http://vlsi.hongik.ac.kr/lecture/com/ucom_ch3_24.pdf
WebMar 23, 2016 · This instruction provides a simple way to execute a program loop a given number of times or for adding a moderate time delay (from 2 to 512 machine cycles) with a single instruction. The following instruction sequence, MOV R2, # 8 TOGGLE: CPL P1.7 DJNZ R2,TOGGLE toggles P1.7 eight times, causing four output pulses to appear at bit … 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

Get out of the loop when TF becomes high. 5. Stop the timer. 6. Clear the TF flag for the next round. 7. Go back to Step 2 to load TH and TL again. Example 1 In the following program, we create a square wave of 50% duty cycle (with equal portions high and low) on the P1.5 bit. Timer 0 is used to generate the time delay. Analyze the program.
WebSince the DJNZ loop test control is at the end of the loop, all the operations for the loop happen on the zeroth time when the loop exits as they do all the previous times. This would be different if the loop test control was at the top (or head) of the loop. Thus, Huisman's answer is correct. Counting from Part1, the loop ends after:
