An instruction is a command for any given task. There are two parts to each instruction; one giving the command and two the operand.
There are 74 instructions in the 8085 microprocessor.
stores next instructions
Intel 8085 is a microprocessor that is used in various electronics devices.
In the 8085 microprocessor, EI stands for "Enable Interrupt." It is an instruction used to enable the interrupt system, allowing the microprocessor to recognize and respond to external interrupt requests. When the EI instruction is executed, the microprocessor sets the interrupt enable flip-flop, permitting it to accept interrupts after the current instruction is completed. This is crucial for handling asynchronous events and multitasking in embedded systems.
because the operand is available in the instruction itself
We can implement "Divided by '2' " operation by using RRC.

In 8085 program counter stores the address of the next instruction which is to be fecthed.same function is performed by instruction pointer in 8086.
There are no instructions in the 8085 that execute in only one clock pulse. The minimum number of clock cycles is four; three for instruction fetch and one for instruction decode/execute.
