(Note2)
-
In case of 1word transmission, set to the “1” for burst size of DMA
controller.
If the amount of data transfer is not an integral multiple of the burst
size, both burst and single transfers are used.
Amount of remaining transfer data ≥ Burst size
Amount of remaining transfer data < Burst size
Start condition:
Enabling the DMAC starts data transfer with no DMAC request
required.
Use condition:
Transfer of all transfer data is complete.
The DMAC channel is disabled.
• Uses burst transfer.
• Uses single transfer
