bit 15

bit 8

U-0

R/W-0

IRQSEL6<6:0>(2)

bit 7

bit 0

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 15

FORCE: Force DMA Transfer bit(1)

= Force a single DMA transfer (Manual mode)

= Automatic DMA transfer initiation by DMA request

bit 14-7

Unimplemented: Read as ‘0’

bit 6-0

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.
