Q: If data is to be sent from an input device to a memory buffer starting at address A000H and ending at AFFFH, provide the mode byte for DMA channel 2.

Check that p is not totally disconnected from the bus throughout the DMA cycle.

Furthermore, the channel is to be reinitialized at the conclusion of each DMA cycle such that the same buffer is filled when the next DMA operation is initiated?
