Figure 19-19. DMA Transfer Flow for Source Address Auto-reloaded and Contiguous Destination Address
19.11 Disabling a Channel Prior to Transfer Completion
32072C–AVR32–2010/03
Under normal operation, software enables a channel by writing a ‘1’ to the Channel Enable Reg-
ister, ChEnReg.CH_EN, and hardware disables a channel on transfer completion by clearing the
ChEnReg.CH_EN register bit.
The recommended way for software to disable a channel without losing data is to use the
CH_SUSP bit in conjunction with the FIFO_EMPTY bit in the Channel Configuration Register
(CFGx) register.
1. If software wishes to disable a channel prior to the DMA transfer completion, then it can
2. Software can now poll the CFGx.FIFO_EMPTY bit until it indicates that the channel
