Detailed explanation-1: -What is the interface circuit? Explanation: Once the address is put on the BUS the interface circuit decodes the address and uses the buffer space to transfer data. 4. The conversion from parallel to serial data transmission and vice versa takes place inside the interface circuits.
Detailed explanation-2: -An interface circuit is a signal conditioning circuit used to bring signal from the sensor up to the format that is compatible with the load device.
Detailed explanation-3: -An interface circuit ensures the translation of an analog to a digital voltage. Sensors transmit a voltage with a low current. The interface circuit converts the voltage into a digital value (0 or 1). The current is low with a sensor signal; Actuators require a higher amperage.
Detailed explanation-4: -Side of the interface which connects to the computer has bus signals for: Address, Data Control Side of the interface which connects to the I/O device has: Datapath and associated controls to transfer data between the interface and the I/O device. This side is called as a “port”.
Detailed explanation-5: -Explanation: The bridge circuit is basically used to extend the processor BUS to connect devices.
