Name:
Access Type:
• CHANN_ENB: Channel Enable Status
0 = if cleared, the DMA channel no longer transfers data, and may load the next descriptor if the DMACONTROLx register
LDNXT_DSC bit is set.
When any transfer is ended either due to an elapsed byte count or a USBA device initiated transfer end, this bit is automat-
ically reset.
1 = if set, the DMA channel is currently enabled and transfers data upon request.
This bit is normally set or cleared by writing into the DMACONTROLx register CHANN_ENB bit field either by software or
descriptor loading.
If a channel request is currently serviced when the DMACONTROLx register CHANN_ENB bit is cleared, the DMA FIFO
buffer is drained until it is empty, then this status bit is cleared.
• CHANN_ACT: Channel Active Status
0 = the DMA channel is no longer trying to source the packet data.
When a packet transfer is ended this bit is automatically reset.
1 = the DMA channel is currently trying to source packet data, i.e. selected as the highest-priority requesting channel.
When a packet transfer cannot be completed due to an END_BF_ST, this flag stays set during the next channel descriptor
load (if any) and potentially until USBA packet transfer completion, if allowed by the new descriptor.
• END_TR_ST: End of Channel Transfer Status
0 = cleared automatically when read by software.
1 = set by hardware when the last packet transfer is complete, if the USBA device has ended the transfer.
Valid until the CHANN_ENB flag is cleared at the end of the next buffer transfer.
• END_BF_ST: End of Channel Buffer Status
0 = cleared automatically when read by software.
1 = set by hardware when the BUFF_COUNT downcount reach zero.
Valid until the CHANN_ENB flag is cleared at the end of the next buffer transfer.
