What Is The Function Of W And Z Registers? They are exclusively used for the internal operation by the microprocessor. These registers are used either to store 8-bit of information in each W and Z registers or a 16-bit data in W, Z register pair with lower order 8-bits in Z and higher-order 8-bits in
What Is The Function Of CLK OUT Pin Of 8085? There are 3 clock signals, i.e. X1, X2, CLK OUT. X1, X2 − A crystal (RC, LC N/W) is connected at these two pins and is used to set frequency of the internal clock generator. This frequency is internally divided by 2. CLK OUT −
Which Type Of Data Transfer Is Not Possible In 8085? Memory to Memory transfer is not possible in microprocessor thats why the instruction MOV M,M is not valid in microprocessor. Which of the data transfer is possible in 8085? The data transfer can be either in two forms namely parallel or serial respectively. By the
Why The Program Counter In 8085 Microprocessor Is A 16 Bit Register? The program counter acts as a pointer to the next instruction to be executed and always contains the 16-bit address of the memory location of next instruction. It is a 16 bit register as 8085 has 16 address lines. Why is the program
Why The Program Counter In A 8085 Microprocessor Is A 16 Bit Register? Why the program counter in a 8085 microprocessor is a 16 bit register? The program counter acts as a pointer to the next instruction to be executed and always contains the 16-bit address of the memory location of next instruction. It is
How Are Interrupts Handled In 8086? Hardware interrupt is caused by any peripheral device by sending a signal through a specified pin to the microprocessor. The 8086 has two hardware interrupt pins, i.e. NMI and INTR. NMI is a non-maskable interrupt and INTR is a maskable interrupt having lower priority. How does a microprocessor handle
What Is Ready Pin? Ready. It is available at pin 22. It is an acknowledgement signal from I/O devices that data is transferred. It is an active high signal. When it is high, it indicates that the device is ready to transfer data. When and where is ready signal used? Ready signal is used in
What Is Microprocessor Speed? The speed at which the microprocessor executes instructions is called clock speed. Clock speeds are measured in MHz or GHz where 1 MHz means 1 million cycles per second whereas 1 GHz equals to 1 billion cycles per second. What is the speed of first generation microprocessor? 1st Generation In 1971,
How Many Active Flags Are There In 8085 Flag Register? In 8085 microprocessor, the flags register How many flags are there in flag register in 8085? In 8085 microprocessor, the flags register can have a total of eight flags. Thus a flag can be represented by 1 bit of information. But only five flags are
How Many Types Of Instructions Are There In 8085? The 8085 (from Intel) is an 8-bit microprocessor. – The 8085 uses a total of 246 bit patterns to form its instruction set. – These 246 patterns represent only 74 instructions. What are the different types of instruction in 8085? The 8085 instruction set is classified
