1.19 +// Test the DMA channel functionality.
1.20 +// API Information:
1.21 +// RBusLogicalChannel, DLogicalChannelBase, DLogicalDevice
1.22 +// Details:
1.23 +// - Load the DMA LDD, create a critical section, an active scheduler and
1.24 +// a CPeriodic object.
1.25 +// - Test one shot single buffer transfers: test simple transfer, request
1.26 +// reconfiguration and cancelling. Verify results are as expected.
1.27 +// - Test one shot double buffer transfers: test simple transfer, request
1.28 +// reconfiguration and cancelling. Verify results are as expected.
1.29 +// - Test streaming single buffer transfers: test simple transfer and
1.30 +// cancelling. Test that framework behaves correctly if one or more DMA
1.31 +// interrupts are missed. Verify results are as expected.
1.32 +// - Test streaming double buffer transfers: test simple transfer and
1.33 +// cancelling. Test that framework behaves correctly if one or more DMA
1.34 +// interrupts are missed. Verify results are as expected.
1.35 +// - Test streaming scatter/gather transfers: test simple transfer and

1.37 +// interrupts are missed. Verify results are as expected.
