The CPU reads the instruction opcode from memory.
★★★★★ (5/5) – The Gold Standard for 8085 Fundamentals. The PPTs based on Gaonkar’s work are considered the most reliable, structured, and pedagogically sound resources for learning the 8085 microprocessor. While the visual design of older slides may feel dated, the content accuracy is unmatched.

B, C, D, E, H, L (8-bit each). They can be paired to perform 16-bit operations (BC, DE, HL).
during an addition operation. This flag is used exclusively for Binary Coded Decimal (BCD) arithmetic.

Always keep a copy of Ramesh Gaonkar's book to clarify concepts presented in the abbreviated slides. ★★★★★ (5/5) – The Gold Standard for 8085
An 8-bit register used to store operands and results.
Bitwise AND, OR, XOR, and compare instructions (e.g., ANA , ORA , XRA , CMP ).
Unidirectional, high-order address lines.
Example: MOV A, B (Copy the 8-bit contents of register B into register A). – Explaining how the ALE signal locks the
Do not just read the assembly code blocks on a slide. Manually track the contents of the Accumulator and Flags on a piece of paper to verify the program logic.
Many Indian technical universities (Visvesvaraya Technological University - VTU, Mumbai University) specifically prescribe Gaonkar. Their internal learning portals sometimes leak the official faculty PPTs.
Hardware interrupts (TRAP, RST 7.5, RST 6.5, RST 5.5, INTR) mapped by priority and masking capability.
An 8-bit register containing 5 active flags (Sign, Zero, Auxiliary Carry, Parity, Carry). 3. The 8085 Bus Structure and Pinout The 8085 uses multiplexing to save pins.
Years later, when Rahul looked back on his journey, he realized that the 8085 had been more than just a microprocessor – it was a catalyst for innovation. The 8085 had empowered him and countless others to create something from scratch, pushing the boundaries of what was thought possible.
