The 8085 contains several registers categorized into general-purpose, special-purpose, and temporary registers:
The time required to complete one operation of accessing memory or an I/O device (e.g., Opcode Fetch, Memory Read, Memory Write). An instruction cycle consists of 1 to 5 machine cycles.
A 16-bit register pointing to a memory location in R/W memory called the "Stack," used for temporary data storage during subroutines. 2. Arithmetic and Logic Unit (ALU) The ALU performs execution data computing. It carries out: microprocessor 8085 ppt by gaonkar
The slide-by-slide format forces a linear, manageable progression. Each slide is a learning unit. The student is not overwhelmed by a wall of text but guided through a series of "aha!" moments. This aligns with cognitive load theory, especially for a subject as inherently sequential as microprocessor operation.

. It alerts external latches (like the 74LS373 IC) to isolate and freeze the lower address bits ( ) from the multiplexed lines.
Data is transferred from one register to another (e.g., MOV A, B ).
