R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-4 Unimplemented: Read as ‘0’
bit 3 RQCOL3: DMA Channel 3 Transfer Request Collision Flag bit
1 = User force and interrupt-based request collision detected
0 = No request collision detected
bit 2 RQCOL2: DMA Channel 2 Transfer Request Collision Flag bit
1 = User force and interrupt-based request collision detected
0 = No request collision detected
bit 1 RQCOL1: DMA Channel 1 Transfer Request Collision Flag bit
1 = User force and interrupt-based request collision detected
0 = No request collision detected
