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
1 = DMA transfers are suspended to allow CPU uninterrupted access to data bus
0 = DMA operates normally
bit 11 DMABUSY: DMA Module Busy bit
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.
