How many pins are present in 8085 and 8086 microprocessor?

Answer 1

There are 256 ports available in the 8085 microprocessor. The IN and OUT instructions have an 8-bit port number, and that is where the 256 comes from.

In order to use ports, the hardware addressing system must decode IO/M-. Some implementations don't do this, so they map IO addresses to memory addresses. In that case, you could say there are 65536 possible IO addresses, but that is not the same as ports, because ports are specific to the IN and OUT instructions.

The other "problem" with IN and OUT is that you cannot specify the address in a register, while you can do so with indirect memory addressing.
