8085 MICROPROCESSOR  PIN CONFIGURATION                    1)  A 8 -A 15   :-              These are address bus and it used for most significant bits of the memory address or 8 bits of input or output address. 2) AD 0 -AD 7   :-              These are multiplexed data/address bus. They are used for dual purpose. They transfer least significant 8 bits (LSB) of the address. Again they are used for data. 3) ALE: -              It is address latch enable signal. It is 1 when address is passed on address bus. 4) IO/ M: -              It is a status signal. When the address and address bus is for I/O device. It is one (high).It is zero (low).When the address on ad...
