8272 Overview
Hand-shaking signals are provided in the 8272 which make DMA operation easy to incorporate with the aid of an external DMA controller chip, such as the 8237. The FDC will operate in either DMA or Non-DMA mode. In the Non-DMA mode, the FDC generates interrupts to the processor for every transfer of a data byte between the CPU and 8272.
