Things Not Taught in School: When They Say It's DMA-Compatible (2)
Not taught in school! An introduction to the specific operation of DMA transfer in a column.
Using the USB controller as an example, I will explain the specific operation of DMA transfer. As an example, let's consider the case of writing to the built-in FIFO of a DMA slave-type USB controller using a general-purpose DMAC. Typically, the capacity of the FIFO built into the USB controller is not very large, generally around the size of two packets at most. *For detailed content of the column, you can view it from the related links.
