hello,
in microprocessor 8085, lower 8 bits of address bus is multiplexed with 8 bit bidirectional data bus in order to reduce the number of pins. but why there are seperate pins for read and write. why not they could not be given as read and write in a single pin by seperating them with active high and low signals respectively.
thanks......
