Frequently Asked Question

Why are there two external DMA channels?

Generally only one DMA channel is used for compresed data input/output.

For Host Interface Pixel Interface [HIPI] mode both channels are used.

Channel 0 is used for uncompressed data input/output and channel 1 is used for compressed data output/input. When using HIPI mode it is recommended to use the DMA channels in a DMA burst configuration.
