The Ultimate Guide to Finding a Free 8085 Microprocessor PPT by R.S. Gaonkar

  • Accumulator (A) – Primary 8-bit register
  • General Purpose Registers (B, C, D, E, H, L) – Can be used as 8-bit or 16-bit pairs (BC, DE, HL)
  • Program Counter (PC) – Holds address of next instruction
  • Stack Pointer (SP) – Points to top of stack
  • Flag Register – Sign, Zero, Auxiliary Carry, Parity, Carry

Good luck with your microprocessor studies!

Slide Set 4: Addressing Modes

  • If you have a legal PDF of Gaonkar's book (library copy), extract key diagrams/tables into your own PPT for personal/educational use.
  • Weakness: If you download an original or older version of "Gaonkar PPTs," the visual design is often outdated.
    • Memory mapping, I/O mapping, 8155/8255 PPI, 8279 keyboard/display
    • Data width: 8-bit ALU, 8-bit registers (grouped as pairs for 16-bit operations).
    • Address bus: 16-bit, addressing 64 KB memory.
    • Clock and power: Single +5V supply, two-phase clock internal generation; maximum clock ~3–6 MHz depending on manufacturer notes.
    • Pinout summary: 40-pin DIP — AD0–AD7 (multiplexed address/data), A8–A15, ALE, RD, WR, IO/M, HOLD, HLDA, INTR, RST7.5/6.5/5.5, TRAP, RESET IN/OUT, SID/SOD, Vcc, GND.
