this instruction is used to add the specified register content to that of the accumulator along with the carry flag value. this instruction is used in processes which involve continuous addition.
We can implement "Divided by '2' " operation by using RRC.
There are 74 instructions in the 8085 microprocessor.
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.
stores next instructions
because the operand is available in the instruction itself

8085 is a microprocessor designed by Intel
b/c the 8085 microprocessor is the first 8 bit microprocessor which Intel is produces in 1877 and this is the first general purpose 8 bit microprocessor. there was an 8 bit general purpose register before 8085 named as 8008 but this microprocessor is not functional 8 bit microprocessor
There are 74 instructions in the 8085 microprocessor.
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 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.
STA 3000H is an 8085 instruction that says to store the accumulator at memory location 3000H.
