PRODUCTION DATA
The DMA controller allows movement of data from one memory address to another without CPU intervention. For example, the DMA controller can be used to move data from the ADC12_A conversion memory to RAM. Using the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces system power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move data to or from a peripheral. Table 9-12 lists the trigger assignments for each DMA channel.
The USB timestamp generator also uses the channel 0, 1, and 2 DMA trigger assignments.
