ANL - Bitwise AND; CJNE - Compare and Jump if Not Equal; CLR - Clear Register; CPL - Complement Register; DA - Decimal Adjust; DEC - Decrement Register; DIV - Divide Accumulator by B; DJNZ - Decrement Register and Jump if Not Zero; INC - Increment Register; JB - Jump if Bit Set; JBC - Jump if Bit Set and Clear Bit
The Instruction Set and Addressing Modes .. DEC. Rn. Decrement Register. 1. 12. DEC direct. Decrement direct byte. 2. 12. DEC. @Ri. Decrement indirect RAM. 1. 12. INC. DPTR. Increment Data Pointer. 1 .. Note: When this instruction is used to modify an output port, the value used as the original port data will be read.

In Direct Addressing mode you specify the operand by giving its actual memory address (in Hexadecimal) or by giving its abbreviated name (e.g. P3). Example: GoBack: DEC. A. ;Decrement A. JNZ. GoBack ;If A is not zero, loop back. The Relative Addressing mode is used with some type of jump instructions like SJMP (
3.1 Types of instructions. The first part of each instruction, called MNEMONIC refers to the operation an instruction performs (copy, addition, logic operation etc.). Mnemonics are abbreviations of the name of operation being executed. For example: INC R1 - Means: . DJNZ Rx,rel, Decrements direct byte and jump if not 0.
Detailed explanation and User Discussion about DJNZ.
Example 3-1. In the program in Example 3-1, the R2 register is used as a counter. The counter is first set to 10. In each iteration the instruction DJNZ decrements R2 and checks its value. If R2 is not zero, it jumps to the target address associated with the label “AGAIN". This.looping action continues until R2 becomes zero.
