This set of 8051 Micro-controller Multiple Choice Questions & Answers (MCQs) focuses on “Jump, Loop and Call Instructions”. 1. “DJNZ R0, label” is ______ DJNZ , ; Function. Decrement and Jump if Not Zero ; Description. DJNZ decrements the location indicated by 1, and branches to the address 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). 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 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
