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.
