of memory. The "5" in 8085 signifies that it operates on a single
Gaonkar categorizes the 8085 instructions into five functional groups: Data Transfer, Arithmetic, Logical, Branching, and Machine Control. These instructions interact with memory through five Addressing Modes Immediate: Data is part of the instruction (e.g., MVI A, 40H Data is stored in registers (e.g., The memory address is specified in the instruction. A register pair (like H-L) holds the memory address. The operand is hidden within the opcode (e.g., for complement accumulator). Conclusion microprocessor 8085 ppt by gaonkar
One of the most intimidating aspects for a beginner. The PPT excels here. It shows the 40-pin DIP package, then zooms in on the multiplexed AD7-AD0 lines. Animated arrows demonstrate how the ALE (Address Latch Enable) signal, in conjunction with an external latch (e.g., 74373), separates the lower-order address from the data. This visual is far more effective than a static diagram. of memory
