Legend:
R = Readable bit
U = Unimplemented bit
W = Writable bit
P = Programmable bit
-n = Bit Value at POR: (‘0’, ‘1’, x = Unknown)
r = Reserved bit
bit 31-16
bit 15
bit 14
bit 13
bit 12
bit 11-0
Reserved: Write ‘0’; ignore read
ON: DMA On bit
1 = DMA module is enabled
0 = DMA module is disabled
FRZ: DMA Freeze bit⁽¹⁾
1 = DMA is frozen during Debug mode
0 = DMA continues to run during Debug mode
Note: FRZ is writable in Debug Exception mode only, it is forced to ‘0’ in Normal mode.
SIDL: Stop in Idle Mode bit
1 = DMA transfers are frozen during Sleep
0 = DMA transfers continue during Sleep
SUSPEND: DMA Suspend bit
1 = DMA transfers are suspended to allow CPU uninterrupted access to data bus
0 = DMA operates normally
Reserved: Write ‘0’; ignore read
