Bit Description R/W Initial State
OUTTknEPdis OUT Token Received When Endpoint Disabled
Applies only to control OUT endpoints. Indicates that an
OUT token was received when the endpoint was not yet
enabled. This interrupt is asserted on the endpoint for which
the OUT token was received.
TimeOUT Timeout Condition
•
In dedicated FIFO mode, applies only to Control IN
endpoints.
•
In Scatter/Gather DMA mode, the TimeOUT interrupt is not
asserted.
Indicates that the core has detected a timeout condition on
the USB for the last IN token on this endpoint.

SetUp
[3]
SETUP Phase Done
Applies to control OUT endpoints only. Indicates that the
SETUP phase for the control endpoint is complete and no
more back-to-back SETUP packets were received for the
current control transfer. On this interrupt, the application can
decode the received SETUP data packet. -
AHBErr [2] AHB Error
Applies to IN and OUT endpoints.
This is generated only in Internal DMA mode if there is an
AHB error during an AHB read/write. The application reads
the corresponding endpoint DMA address register to get the
error address. R_SS

EPDisbld [1] Endpoint Disabled Interrupt
Applies to IN and OUT endpoints.
This bit indicates that the endpoint is disabled per the
application’s request. R_SS

XferCompl [0] Transfer Completed Interrupt (XferCompl) Applies to IN and
OUT endpoints.
•
When Scatter/Gather DMA mode is enabled
•
For IN endpoint this field indicates that the requested data
from the descriptor is moved from external system memory
to internal FIFO.
•
For OUT endpoint this field indicates that the requested
data from the internal FIFO is moved to external system
memory. This interrupt is generated only when the
corresponding endpoint descriptor is closed, and the IOC bit
for the corresponding descriptor is set.
•
When Scatter/Gather DMA mode is disabled, this field
indicates that the programmed transfer is complete on the
AHB as well as on the USB, for this endpoint.
