Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

FORCE: Force DMA Transfer bit⁽¹⁾
1 = Force a single DMA transfer (Manual mode)
0 = Automatic DMA transfer initiation by DMA request
Unimplemented: Read as ‘0’
IRQSEL<6:0>: DMA Peripheral IRQ Number Select bits⁽²⁾
0000000-1111111 = DMAIRQ0-DMAIRQ127 selected to be Channel DMAREQ
Note 1: The FORCE bit cannot be cleared by the user. The FORCE bit is cleared by hardware when the forced
DMA transfer is complete.
2: Please see Table 8-1 for a complete listing of IRQ numbers for all interrupt sources.
