Microprocessor
When RET instruction is executed by any subroutine then

the PC will be incremented after the execution of the instruction.

without any operation, the calling program would resume from instruction immediately following the call instruction and also the PC will be incremented after the execution of the instruction.

without any operation, the calling program would resume from instruction immediately following the call instruction.

the top of the stack will be popped out and assigned to the PC.

The reason for the presence of ALE pin in 8085, but not in 6800 is that

8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O

8085 has multiplexed bus, whereas 6800 does not have

8085 has 5 interrupts lines, whereas 6800 has only two
