What is hex code in microprocessor?
Hexadecimal (base 16 – 0 1 2 3 4 5 6 7 8 9 A B C D E F) is used as a shortcut notation for binary numbers (0 1) because it works out nicely for 8, 16, 32, and 64 bit processors. Simple answer: Hex is encoding 4 binary digits into one hex digit, and is easier to read than strings of 0s and 1s.
How can I learn 8085 microprocessor program?
Add two 8-bit numbers
- LXI H, 2501H : “Get address of first number in H-L pair. Now H-L points to 2501H”
- MOV A, M : “Get first operand in accumulator”
- INX H : “Increment content of H-L pair.
- ADD M : “Add first and second operand”
- INX H : “H-L points 4002H”
- MOV M, A : “Store result at 2503H”
- HLT : “Stop”
What is the memory in 8085?
The memory capacity is 64 KB. Also 8085 Can Perform Operation Upto 2^8 ie. 256 numbers. A number greater than this is to taken multiple times in 8 bit data bus.
Which pin is marked as the master reset RST function in microcontroller IC 8051?
Pin 9
Pin 9 (RST): Pin 9 is the Reset Input Pin. It is an active HIGH Pin i.e. if the RST Pin is HIGH for a minimum of two machine cycles, the microcontroller will be reset.
Which circuits uses microcontroller?
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.
What is hex code?
Hex color codes are values that tell the display how much of a color to show. The values are a special code that represents color values from 0 to 255. If red, green, and blue are all at the maximum 255 (represented as “ff” in the code), the color expressed is the color white.
How do you find the hex code of an instruction?

How do you code a microprocessor?
5.1 Microcomputer Programming Languages Microprocessors are typically programmed using semi-English-language statements (assembly language). In addition to assembly languages, microcomputers use a more understandable human-oriented language called high-level language.
How is 8086 microprocessor different from 8085 microprocessor explain?
