What else can I help you with?
How do you add and subtract 16 bit numbers using 8051 microprocessor?
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
Is microprocessors use in inverters?
Microprocessor is used where we require more m/m and data. microcontroller is best option for inverters,but in a case if we want to improve, or want to make it advance such as with some conditions then we use microprocessor
What is the use of command MOV A A in 8085 microprocessor?
The MOV A,A instruction in the 8085 does nothing, not even change flags. It only consumes time, specifically four clock cycles plus applicable wait states.
What is meaning of 8085 microprocessor?
8085 is a 8 bit microprocessor designed by Intel.
Can you use microcontroller instead of microprocessor?
as the name suggests processors does the process only. basically CPU does the process only but controllers processes as well as controls so that's why we are using processors.
What is the use of NOP instruction in 8085?
The NOP (No Operation) instruction takes time but does nothing to the data or the status of the microprocessor. When executed in a loop, it can take substantial time, from microseconds, to milliseconds, to seconds.
How many pins are present in 8085 and 8086 microprocessor?
There are 256 ports available in the 8085 microprocessor. The IN and OUT instructions have an 8-bit port number, and that is where the 256 comes from.In order to use ports, the hardware addressing system must decode IO/M-. Some implementations don't do this, so they map IO addresses to memory addresses. In that case, you could say there are 65536 possible IO addresses, but that is not the same as ports, because ports are specific to the IN and OUT instructions.The other "problem" with IN and OUT is that you cannot specify the address in a register, while you can do so with indirect memory addressing.
What is NOP Instruction stands in 8085 microprocessor?
The NOP instruction is a no-operation instruction. It does nothing to the state of the machine, except to use some time. In the case of the 8085, it uses four clock cycles plus however many wait states are need to access the NOP instruction from memory.
What is memory mapped in 8085?
memory interfacing in 8085 microprocessor refers to provide a intermediate mode of transferring or receiving data from registers to main memory
Which microprocessor did sputnik use?
Sputnik did not use a microprocessor.
How data transfer operation is done in 8085 micro processor?
Data transfer in the 8085 microprocessor can be done with the help of several instructions like the MOV,MVI,OUT and IN . Lets say, we want to move the contents of a register R1 to register R2, then we could use the instruction MOV R2,R1 ; and so on...
What is the use of RST?
RSTn(0-7) is software interrupt & RST(7.5,6.5,5.5) are INTEL's 8085 maskable interrupts their priority is respectively 7.5,6.5,5.5.RSTn.5 is hardware intterrupt and it is controlled by the external pin available on the chip of 8085. it is used to interrupt the microprocessor from its normal execution and tends to execute some ISR(interrupt service routine)
