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: Refer to Table 7-1 for a complete listing of IRQ numbers for all interrupt sources.
