ADVANCE INFORMATION
The direct memory access (DMA) controller allows movement of data from one memory address to another without CPU intervention. For example, the DMA can be used to move data from ADC conversion memory to SRAM. The DMA reduces system power consumption by allowing the CPU to remain in low power mode, without having to awaken to move data to or from a peripheral.
The DMA in these devices support the following key features:
Table 8-2 lists the available triggers for the DMA which are configured using the DMATCTL.DMATSEL control bits in the DMA memory mapped registers.
TRIGGER 0:6 | SOURCE |
---|---|
0 | Software |
1 | Generic Subscriber 0 (FSUB_0) |
2 | Generic Subscriber 1 (FSUB_1) |
3 | ADC0 Publisher 2 |
