8085 Microprocessor and its Operation

 . The 8085 microprocessor is an 8 bit microprocessor designed by Intel and introduced in 1976. It is a widely used microprocessor in embedded systems and educational settings due to its simplicity and effectiveness. Here's an overview of its architecture and operation: Data Bus: 8-bit: It can handle 8 bits of data at a time, which means it processes 1 byte of data in a single operation. Address Bus: 16-bit: It can address up to  2 16 2 16  = 65,536 memory locations, which translates to 64KB of addressable memory. Registers: General Purpose Registers:  6 registers (B, C, D, E, H, L) which can be used individually or in pairs (BC, DE, HL) for 16-bit operations. Accumulator:  An 8-bit register (A) used for arithmetic and logic operations. Flag Register:  Contains flags that indicate the status of the processor (Zero, Carry, Sign, Parity, and Auxiliary Carry Flags). Program Counter (PC): 16-bit register that holds the address of the next instruction to be exec...
