Block Diagram of Memory and that iOrTo Interfacing 8085 Interfacing Pins If we are executing any instruction, we want the micro-processor to gain access to the memory for studying instruction codes and also the data kept in the memory. As mentioned earlier, the 8085 gives 8 bit I/O address. This means it can select one of the 256 I/O ports. To select an appropriate I/O device, it is necessary to do following things. 1. Decode the address to generate unique signal corresponding to the device address on the bus. 2. When device address … Meer weergeven The microprocessor 8085 accepts 8 bit data from the input device such as keyboard, sensors, transducers etc. Fig. 4.33 (see Fig. on next page) shows the circuit diagram to Input Output Interfacing Techniques … Meer weergeven The microprocessor 8085 sends 8 bit data to the output device such as 7 segment displays, LEDs, printer etc. Fig 4.34 shows the circuit diagram to interface output port (latch) which … Meer weergeven In memory mapped I/O, MEMR (memory read) and MEMW (memory write) control signals are required to control the data transfer between I/O device and microprocessor. … Meer weergeven In memory mapped I/O, the I/O devices are assigned and identified by 16 bit addresses.
