Is Program Counter A Special Purpose Register? Special Purpose Registers: PC (Program Counter) – address of the instruction being executed. Which of the following is not considered as special purpose register? 5. Which of the following is not a special function register? Explanation: Accumulator is a general function register, which can be used for multiple
How Does A 8-bit Shift Register Work? The SN74HC595N is a simple 8-bit shift register IC. Simply put, this shift register is a device that allows additional inputs or outputs to be added to a microcontroller by converting data between parallel and serial formats. … Essentially it takes 8 bits from the serial input and
What Are Segments Register? Segment registers are basically memory pointers located inside the CPU. Segment registers point to a place in memory where one of the following things begin: Data storage. Code execution. What is the role of segment register? A segment register changes the memory address accessed by 16 bits at a time, because
What Are The Types Of Register? There are different types of Registers that are used. Some of the most used Registers are accumulator, data register, address register, program counter, memory data register, index register, and memory buffer register. The various operations are performed with the use of register. What are the types of register and
What Are The Various Register In 8085? The 8085 has six general – purpose registers to store 8-bit data; these are identified as B, C, D, E, H and L as shown in the figure. They can be combined as register pairs – BC, DE, and HL – to perform some 16-bit operations. What are
What Are The Different Ways To Clear The Accumulator? S.No. MNEMONICS COMMENT 1 MVI A, 00 A <- 00 2 ANI 00 A AND 00 3 XRA A A XOR A 4 SUB A A <- A – A Which instruction stands for clear accumulator? In 8085 Instruction set, STA is a mnemonic that stands
What Are The Types Of CPU Registers? Accumulator: … Memory Address Registers (MAR): … Memory Data Registers (MDR): … General Purpose Registers: … Program Counter (PC): … Instruction Register (IR): What are the different types of register? There are different types of Registers that are used. Some of the most used Registers are accumulator, data
What Are The Special Functions Associated With Register CX? CX is known as the count register, as the ECX, CX registers store the loop count in iterative operations. DX is known as the data register. It is also used in input/output operations. It is also used with AX register along with DX for multiply and
What Does LDA Mean In Assembly Language? LDA (short for “LoaD Accumulator“) is the mnemonic for a machine language instruction which retrieves a copy from the specified RAM or I/O address, and stores it in the accumulator. What is LDA and STA? STA is for copying data from accumulator to memory location, LDA is for
What Do Registers Do? Registers. Registers are also called internal memory or immediate access memory stores. A register is a small amount of fast temporary memory within the processor where the ALU or the CU can store and change values needed to execute instructions. What are the benefits of registers? Advantages. Below are the advantages:
