JC 3000H (Jump to address 3000H only if the Carry flag is set to 1)
Goes high to indicate that the lower-order bus holds an address.
To separate data from addresses, an external latch IC (such as the 74LS373) is required:
The is more than just a collection of slides; it is a rite of passage for engineers. While the 8085 is technologically obsolete, its architecture perfectly explains the von Neumann bottleneck, register management, and instruction pipelining basics. microprocessor 8085 ppt by gaonkar

High-performance Metal-Oxide-Semiconductor (HMOS) Integration: 40-pin Dual In-line Package (DIP) 2. Hardware Architecture and Functional Blocks
This article provides an exhaustive analysis of the 8085 microprocessor, structuring the core concepts found in a premium "Gaonkar-style" presentation (PPT). It covers architectural design, the internal register structure, instruction sets, and interrupt handling. 1. Introduction to the 8085 Microprocessor JC 3000H (Jump to address 3000H only if
