Input Output Interfacing 8085 MicroprocessorInput Output Interfacing 8085 Microprocessor : Any application of a microprocessor based system requires the transfer of data between external circuitry to the microprocessor and microprocessor to the external circuitry. User can give information to the microprocessor (Read More)


Input Output Interfacing 8085 MicroprocessorInput Output Interfacing Techniques : The most of the microprocessors support isolated I/O system. It partitions memory from I/O, via software, by having instructions that specifically access (address) memory, and others that specifically access I/O. When these instructions are decoded (Read More)


Input Output Transfer Techniques : In Input Output Transfer Techniques, the system requires the transfer of data between external circuitry and the microprocessor. In this section, we will discuss different ways of I/O transfer. Program controlled I/O or Polling control . Interrupt program controlled I/O or interrupt driven I/O. Hardware controlled I/O. I/O controlled by Handshake signals. I/O controlled by ready signal. (Read More)
