In Intel 8085 microprocessor ALE signal is made high to _______________. A) fetch the instruction B) increment the program counter C) enable the data bus to be used as higher order address bus D) enable the data bus to be used as low order address bus
Question
In Intel 8085 microprocessor ALE signal is made high to _______________. A) fetch the instruction B) increment the program counter C) enable the data bus to be used as higher order address bus D) enable the data bus to be used as low order address bus
Solution
The ALE (Address Latch Enable) signal in the Intel 8085 microprocessor is made high to enable the data bus to be used as a higher order address bus. This is because the Intel 8085 uses a multiplexed data bus for both data and address. The ALE signal is used to de-multiplex the address and data bus. When the ALE signal is high, the address is latched into an external latch and the data bus is free to be used as a higher order address bus.
