: An 8-bit register containing 5 status flags: Sign (S), Zero (Z), Auxiliary Carry (AC), Parity (P), and Carry (CY). Universiti Sains Malaysia Module 3: Instruction Set & Addressing Modes Instruction Groups Data Transfer : MOV, MVI, LDA, STA. Arithmetic : ADD, SUB, INR, DCR. : ANA, ORA, XRA, CMP. : JMP, JC, JNC, CALL, RET. Machine Control : HLT, NOP. Addressing Modes : Data is part of the instruction (e.g., MVI A, 05H : Data is in a register (e.g., : Address of data is given in the instruction (e.g., : Address is stored in a register pair (e.g., mfulecollegewarud.ac.in Module 4: Interrupts & Interfacing EEE226 - School of Electrical and Electronic Engineering
Data is provided directly in the instruction (e.g., MVI A, 05H ).
When searching for a new version of Gaonkar’s PPT (as of 2024-2025), you should expect modernizations that the original 1998 floppy-disk PPTs did not have. microprocessor 8085 ppt by gaonkar new
Indicates that the processor is being reset; can be used to reset peripheral devices. Serial I/O Ports:
: Resets the Program Counter (PC) to zero and resets the interrupt enable flip-flops. : An 8-bit register containing 5 status flags:
The most successful PPTs start with a clear, functional definition: The microprocessor is a programmable device that takes in numbers, performs arithmetic or logical operations according to the program stored in memory, and then produces other numbers as a result .
