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

bit 31-16 Unimplemented: Read as ‘0’

bit 15 ON: DMA On bit(1)

1 = DMA module is enabled

0 = DMA module is disabled

bit 14-13 Unimplemented: Read as ‘0’

bit 12 SUSPEND: DMA Suspend bit

bit 11

1 = DMA transfers are suspended to allow CPU uninterrupted access to data bus

0 = DMA operates normally

DMABUSY: DMA Module Busy bit(4)

1 = DMA module is active

0 = DMA module is disabled and not actively transferring data

bit 10-0 Unimplemented: Read as ‘0’

Note 1: When using 1:1 PBCLK divisor, the user’s software should not read/write the peripheral’s SFRs in the

SYSCLK cycle immediately following the instruction that clears the module’s ON bit.
