What do you mean by polling in 8085.
When the microprocessor receives an Interrupt Service Request (ISR) on the interrupt line it must determine which of the devices connected to that input sent the request.
Software Polling is one method by which it can do so.
In Software Polling:
A software routine is used to identify the device requesting service. It does so by checking each device to see if it was the one needing service.
