Answer / Rajni Pandey
The address bus in the 8085 is tri-stated, meaning it can be put into a high impedance state by the microcontroller to prevent driving data onto other devices during certain states. This is done to save power consumption. It is also unidirectional as data can only flow from the CPU to the external memory or I/O devices.
