Hi,
Ale differentiates between address and data for the processor.ALE is high initially, When ALE goes low the contents on the port are latched and considered as address.

8085 has 5 hardware interrupts and 7 software interrupts. Hardware interrupts are the interrupts generated external to the processor. Software interrupts are the interrupts created internelly that means through software
