The MA31753 DMA controller has 4 channels from which independant transfers can be executed.
These channels have programmable priorities and can be masked.
They can also be enabled and disabled under software control.
The data can be transferred in several modes - single word mode, double word mode a
MA31753 MA31753 DMA Controller (DMAC) For An MA31750 System Replaces June 1999 version, DS3825-4.0 DS3825-5.0 January 2000 The MA31753 Direct Memory Access Controller (DMAC) is a peripheral interface circuit design primarily for use with the MA31750 microprocessor.
Each DMAC provides up to four independant, prioritised channels each of which can perform DMA transfers between memory and/or I/O devices using the MA31750 bus.
Each channel has its own programmable internal priority and can be mask
