Legend:
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 31-11
Unimplemented: Read as ‘0’
bit 10-9 DMABRSTM<1:0>: DMA Burst Mode Selection bit
11 = Burst Mode 3: INCR16, INCR8, INCR4 or unspecified length
10 = Burst Mode 2: INCR8, INCR4 or unspecified length
01 = Burst Mode 1: INCR4 or unspecified length
00 = Burst Mode 0: Bursts of unspecified length
bit 8 DMAERR: Bus Error bit
1 = A bus error has been observed on the input
0 = The software writes this to clear the error
bit 7-4 DMAEP<3:0>: DMA Endpoint Assignment bits
These bits hold the endpoint that the DMA channel is assigned to. Valid values are 0-7.
bit 3 DMAIE: DMA Interrupt Enable bit
1 = Interrupt is enabled for this channel
0 = Interrupt is disabled for this channel
bit 2 DMAMODE: DMA Transfer Mode bit
1 = DMA Mode1 Transfers
0 = DMA Mode0 Transfers
bit 1 DMADIR: DMA Transfer Direction bit
1 = DMA Read (TX endpoint)
0 = DMA Write (RX endpoint)
bit 0 DMAEN: DMA Enable bit
1 = Enable the DMA transfer and start the transfer
0 = Disable the DMA transfer
