CHAPTER  12    DMA  FUNCTIONS

User’s Manual  U13850EJ6V0UD

462

12.5 Operation

When a DMA transfer request is generated during CPU processing, DMA transfer is started after the current CPU

processing has finished.  Regardless of the transfer direction, 4 CPU clocks (f

CPU

) are required for one DMA transfer.

The 4 CPU clocks are divided as follows.

•

Internal RAM access: 1 clock

•

Peripheral I/O access: 3 clocks

After one DMA transfer (8/16 bits) ends, control always shifts to the CPU processing.

A DMA transfer operation timing chart is shown below.

Remark

n = 0 to 5

If two or more DMA transfer requests are generated simultaneously, the DMA transfer requests are executed in

accordance with the following priority order: DMA0 > DMA1 > DMA2 > DMA3 > DMA4 > DMA5.  While a higher

priority DMA transfer request is being executed, the lower priority DMA transfer requests are held pending.  After the

higher priority DMA transfer ends, control always shifts to the CPU processing once, and then the lower priority DMA

transfer is executed.

The processing when the transfer requests DMA0 to DMA5 are generated simultaneously is shown below.
