Copies data from a source location to a destination location without altering its contents. (Examples: MOV , MVI , LXI , LDA , STA ).

Built using NMOS (N-channel Metal-Oxide-Semiconductor) technology.

during an addition operation. This flag is used exclusively for Binary Coded Decimal (BCD) arithmetic.

Example: MVI A, 32H (Move immediate hex value 32 directly into the Accumulator).

The 8085 includes five status flags that change based on the results of ALU operations:

specifies whether the operational target is an input/output device (High) or memory (Low). When paired with S1cap S sub 1 S0cap S sub 0 , they reveal the exact operation status: S1cap S sub 1 S0cap S sub 0 Machine Cycle Operation Opcode Fetch Memory Read Memory Write Slide 7: The 8085 Interrupt Structure Interrupt Management in 8085

Many Indian universities (VTU, JNTU, Anna University) host free 8085 PPTs.

However, students often search for a digital shortcut: They want the structured, reliable content of Gaonkar’s teaching methodology delivered in a crisp, slide-by-slide presentation format.

Leave a comment below describing which chapter of Gaonkar you need (e.g., "Stack and Subroutines" or "8259 PIC"), and we will guide you to a direct source. Happy coding in Assembly!
