21 / 101 page ![]() MSP430F563x www.ti.com SLAS650A – JUNE 2010 – REVISED JULY 2010 DMA Controller 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. The USB timestamp generator also utilizes the channel 0, 1, and 2 DMA trigger assignments described in Table 11. Table 11.
