DMA Channel Map 

The equivalent of two 8237A DMA controllers are implemented in the FB2652 board.  
Each controller is a four-channel DMA device that will generate the memory 
addresses and control signals necessary to transfer information directly between a 
peripheral device and memory. This allows high speeding information transfer with less 
CPU intervention.  The two DMA controllers are internally cascaded to provide four 
DMA channels for transfers to 8-bit peripherals (DMA1) and three channels for 
transfers to 16-bit peripherals (DMA2).  DMA2 channel 0 provides the cascade 
interconnection between the two DMA devices, thereby maintaining IBM PC/AT 
compatibility. 

The following is the system information of DMA channels: 

DMA Controller 1 

DMA Controller 2 

Channel 0: Spare 

Channel 4: Cascade for 
controller 1 

Channel 1: Reserved for 
IBM SDLC 

Channel 5: Spare 

Channel 2: Diskette 
adapter 

Channel 6: Spare 

Channel 3: Spare 

Channel 7: Spare
