DJNZ , ; Function. Decrement and Jump if Not Zero ; Description. DJNZ decrements the location indicated by 1, and branches to the address 8051 Instruction Set: DJNZ Description: DJNZ decrements the value of register by 1. If the initial value of register is 0, decrementing the value will cause Looping in the 8051 Repeating a sequence of instructions a certain number of times is called a loop. An instruction DJNZ reg, label is used to perform a Loop This set of 8051 Micro-controller Multiple Choice Questions & Answers (MCQs) focuses on “Jump, Loop and Call Instructions”. 1. “DJNZ R0, label” is ______ DJNZ 60H, LABEL_3 will cause a jump to the instruction at label LABEL2 with the values 00H, 6FH, and 15H in the three. RAM locations.Description: DJNZ decrements the value of register by 1. If the initial value of register is 0, decrementing the value will cause it to reset to 255 (0xFF Hex).
