AD0–AD7: Multiplexed address/data lines. This saves pins by using the same lines for the lower 8 bits of the address and the 8-bit data. A8–A15: Higher-order address lines. Control and Status Signals

Example: ADD B (Add B to Accumulator), ANA C (Logical AND C with Accumulator). Branching Instructions These alter the flow of the program. Example: JMP 2000H (Jump to address 2000H), CALL , and RET . Interfacing and Applications microprocessor 8085 ppt by gaonkar

ALE (Address Latch Enable): Used to demultiplex the AD0–AD7 bus. AD0–AD7: Multiplexed address/data lines

Accumulator (A): An 8-bit register that is part of every ALU operation. HL) to hold 16-bit data.

General Purpose Registers: B, C, D, E, H, and L. These can be used individually or as pairs (BC, DE, HL) to hold 16-bit data.
