DMA stands for Direct Memory Access, in regards to 8085 MP. It consists of 2 pins, namely, HOLD and HLDA. The former of which indicates the processor that either a peripherial or any IO device, is requesting the processor to hold its current activites and give the control of buses to IO devices. HLDA, on the contrary, is the acknowledgement from the microprocessor to the concerned IO device sending the request.
