• SOD
0 (DISABLE): STOP ON DONE disabled, the descriptor fetch operation ignores DONE Field of CTRLA register.
1 (ENABLE): STOP ON DONE activated, the DMAC module is automatically disabled if DONE FIELD is set to 1.
• LOCK_IF
0 (DISABLE): Interface Lock capability is disabled
1 (ENABLE): Interface Lock capability is enabled
• LOCK_B
0 (DISABLE): AHB Bus Locking capability is disabled.
1(ENABLE): AHB Bus Locking capability is enabled.
• LOCK_IF_L
0 (CHUNK): The Master Interface Arbiter is locked by the channel x for a chunk transfer.
1 (BUFFER): The Master Interface Arbiter is locked by the channel x for a buffer transfer.
• AHB_PROT
AHB_PROT field provides additional information about a bus access and is primarily used to implement some level of
protection.
