DRDY0
Channel 0 Destination Ready Flag
Set by hardware when the destination peripheral of channel 0 is ready.
Cleared by hardware when the destination peripheral of channel 0 is not ready.
2
SRDY0
Channel 0 Source Ready Flag
Set by hardware when the source peripheral of channel 0 is ready.
Cleared by hardware when the source peripheral of channel 0 is not ready.
1
EOFI0
Channel 0 End Of Data Flow Interrupt Flag
Set by hardware at the end of a channel 0 data flow transfer.
Cleared by software by setting EOFIA0 in DFCCON. Can not be set by software.
0
DFBSY0
Channel 0 Busy Flag
Set by hardware when a transfer is on-going on channel 0.
Cleared by hardware when no transfer is on-going on channel 0.
