Chapter 8 DMA Controller (DMAC)
Note
8.1 Features
Preliminary User’s Manual U17566EE1V2UM00
The microcontroller includes a direct memory access (DMA) controller (DMAC)
that executes and controls DMA transfers.
Throughout this chapter, the individual channels of the DMA Controller are
identified by “n”.
The DMAC controls data transfer between memory and I/O or among I/Os,
based on DMA requests issued by the on-chip peripheral I/O, or software
triggers.
• Four independent DMA channels
• Transfer units: 8, 16 and 32 bits
• Maximum transfer count: 65536 (2
• Two transfer modes independently selectable for each DMA channel
• Transfer requests
• Transfer objects
• DMA transfer completion flag
• Automatic restart function
• Forcible DMA termination by NMI
