What is a byte instruction?
In 1-byte instruction, the opcode and the operand of an instruction are represented in one byte. A one-byte instruction includes a opcode and a operand in the same byte. If there is no numeral present in the instruction then that instruction will be of one-byte. for example, MOV C, A, RAL, and ADD B, etc.
Which of the following is a three byte instruction in 8085 microprocessor?
In a 3-byte instruction, the first byte specifies the opcode, and the following two bytes specify the 16-bit address. The 2nd byte holds the low order address. The 3rd-byte holds the high order address. Instructions require three memory locations to store the single byte in the memory.
How many commands are there in 8085?
An instruction is a binary pattern designed inside a microprocessor to perform a specific function. The entire group of instructions that a microprocessor supports is called Instruction Set. 8085 has 246 instructions. Each instruction is represented by an 8-bit binary value.
What is stored in registers Mcq?
A set of register which contain are: data. memory addresses. result.
How many types of registers are Sanfoundry?
Explanation: There are 4 types of shift registers, viz., Serial-In/Serial-Out, Serial-In/Parallel-Out, Parallel-In/Serial-Out and Parallel-In/Parallel-Out.
Why latches are called a memory devices?
Why latches are called memory devices? Explanation: Latches can be memory devices, and can store one bit of data for as long as the device is powered. Once device is turned off, the memory gets refreshed. Explanation: A latch has two stable states, following the principle of Bistable Multivibrator.
What does flipflop mean?
1 : the sound or motion of something flapping loosely. 2a : a backward handspring. b : a sudden reversal (as of policy or strategy) 3 : a usually electronic device or a circuit (as in a computer) capable of assuming either of two stable states.

What is Flip Flop with example?
Figure 3 shows the logic symbol of the SR flip-flop. Notice that the gate input is denoted as E for Enable and it has the same functionality as G discussed above. Figure 3: Gated SR-latch. When the square signal is a square wave we call it a clock and we call the latch a clocked latch….The SR-Latch.
