H.W) specify the mode byte for DMA channel 2 if it

H.W) specify the mode byte for DMA channel 2 if it is to transfer data from an input device to a memory buffer starting at address AOOOH and ending at AFFFH. Ensure that up is not completely locked off the bus during the DMA cycle. Moreover, at the end of each DMA cycle, the channel is to be reinitialized so that the same buffer is to be filled when the next DMA operation is initiated
