DMA
μ
DMA is the simplified DMA which has the equivalent function to EI
2
OS function
μ
DMA has DMA transfer channel
which consists of 16 channels and has the following functions.
Automatic data transfer between peripheral resources (I/O) and memory.
CPU program executing stops dring DMA operation.
Selectable for address transfer increase/decrease .
DMA transfer control is done at DMA enable register, DMA stop status register, DMA status register and
descriptor.
Stop request stops DMA transfer from resources.
After DMA transfer, flag is set to bit corresponding to DMA status register transfer stop channel and stop
interrupt is output to interrupt controller.
