WebInterrupt-driven I/O Device controller does most of the work, notifies CPU when done. CPU still has to extract data itself. DMA-based I/O DMA controller takes over CPU's role, interrupts CPU when data is available in memory. Advantage: minimum load on CPU, especially in the form of fewer interrupts since DMA controller can do more buffering. http://inputoutput5822.weebly.com/interrupt-driven-io.html#:~:text=For%20input%2C%20the%20device%20interrupts%20the%20CPU%20when,data%20or%20to%20acknowledge%20a%20successful%20data%20transfer.

WebApr 22, 2016 · When the output goes low, it is actively "pulled" to ground. Conversely, when the output is set to high, it is actively "pushed" toward Vcc. Simplified, it looks like this: An Open-Drain output, on the other hand, is only active in one direction. It can pull the pin towards ground, but it cannot drive it high.
