: A comprehensive 330-slide presentation that closely follows the book's structure, covering architecture, programming, and interfacing.
The total time required to complete the execution of an instruction.

A positive-going pulse generated at the beginning of every machine cycle. It signals external hardware (like a 74LS373 latch) to hold the lower 8 bits of the address ( ), freeing up the lines to transform into data lines ( ) for the remainder of the cycle.

These instructions alter the sequential flow of program execution by changing the values in the Program Counter. They can be unconditional or conditional upon status flags. the pin diagrams
Built using NMOS (N-channel Metal-Oxide-Semiconductor) technology.
– Practical code examples for the 5 modes.
Pins 12-19 handle both the lower 8 bits of the address and the 8 bits of data. The ALE (Address Latch Enable) signal de-multiplexes these lines. and Applications with the 8085 .
Set if an arithmetic operation generates a carry or borrow out of the MSB. Slide 5: Demultiplexing the Address/Data Bus
The is an incredible starting point . It gives you the high-level architecture, the pin diagrams, and the instruction sets in a visual format.
