There is no exit instruction in the 8085. Do you mean return, as in from a function or interrupt? If so, the instruction is RET.
Not in the 8085.
it is the standard usded by the INTEL to categorize their microprocessors.
There are 74 instructions in the 8085 microprocessor.
MUL is not an 8085 instruction.
Ten microprocessors are the 4004, 4040, 8008, 8080, 8085, 8086, 8088, 80286, 80386, and 80486.There are many more, and this list only included some of the Intel microprocessors, in mostly historical order.
E.g. 8085, 8086, 8255, 8051, 6800, 8257, 8251 and many more...
CALL, requiring 18 clock cycles.
There are 74 instructions in the 8085 microprocessor.
The NOP instruction is a no-operation instruction. It does nothing to the state of the machine, except to use some time. In the case of the 8085, it uses four clock cycles plus however many wait states are need to access the NOP instruction from memory.
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.
stores next instructions
The 8085 is an 8 bit processor, so its word length is 8 bits.
