11.1 Summary of DMA Operations

The DMA Controller is capable of moving data between addresses according to a number of different parameters. Each of these parameters can be independently configured for any transaction. In addition, any or all of the DMA channels can independently perform a different transaction at the same time. Transactions are classified by these parameters:

• Source and destination (SFRs and data RAM)
• Data size (byte or word)
• Trigger source
• Transfer mode (One-Shot, Repeated or 
Continuous)
• Addressing modes (Fixed Address or 
Address Blocks with or without Address 
Increment/Decrement)

In addition, the DMA Controller provides channel priority arbitration for all channels.
