Description
Channel [n] Alternate Clear
Value Description
0 No effect.
1 Setting a bit clears the corresponding SET[n] bit in the
DMAALTSET register meaning that channel [n] is using the
primary control structure.
Note:
For Ping-Pong and Scatter-Gather cycle types, the µDMA
controller automatically sets these bits to select the alternate
channel control data structure.
