line goes low. The microprocessor reads the opcode from the memory data bus.

Categorizing the entire 246-opcode language structure into functional buckets. microprocessor 8085 ppt by gaonkar free

Operations that add, subtract, increment, or decrement data (e.g., ADD , ADI , SUB , INR , DCR ). line goes low

Sign Flag (S): Set if the result is negative.Zero Flag (Z): Set if the result is zero.Auxiliary Carry Flag (AC): Set if there is a carry from bit D3 to D4.Parity Flag (P): Set if the result has an even number of ones.Carry Flag (CY): Set if there is a carry from the most significant bit. Instruction Set and Programming Operations that add, subtract, increment, or decrement data

Gaonkar classifies the 8085 instruction set into five functional groups based on the types of operations they perform. 1. Data Transfer Instructions

Example Program 2: Block Data Transfer (Indirect Addressing Model)
