The instructions are the "language" of the processor. Gaonkar classifies them into functional categories. Data Transfer Instructions

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. microprocessor 8085 ppt by gaonkar

Accumulator (A): An 8-bit register that is part of every ALU operation. The instructions are the "language" of the processor

The 8085 remains the perfect "sandbox" for students to understand how a CPU thinks before moving on to complex 64-bit architectures. These can be used individually or as pairs

The 8085 has five status flags that reflect the result of an ALU operation: Sign (S): Set if the result is negative. Zero (Z): Set if the result is zero. Auxiliary Carry (AC): Used for BCD arithmetic. Parity (P): Set if the result has an even number of 1s. Carry (CY): Set if an operation results in a carry-out. Pin Configuration and Signals
