Warning: When RX_DATA_BK0 and RX_DATA_BK1 are both set, there is no way to determine
which one to clear first. Thus the software must keep an internal counter to be sure to clear alter-
natively RX_DATA_BK0 then RX_DATA_BK1. This situation may occur when the software
application is busy elsewhere and the two banks are filled by the USB host. Once the application
comes back to the USB driver, the two flags are set.
A stall handshake can be used in one of two distinct occasions. (For more information on the
stall handshake, refer to Chapter 8 of the Universal Serial Bus Specification, Rev 2.0.)
The following procedure generates a stall packet:
11. The microcontroller notifies the USB device it has finished the transfer by clearing
12. A fourth Data OUT packet can be accepted by the USB device and copied in the FIFO
• A functional stall is used when the halt feature associated with the endpoint is set. (Refer to
• To abort the current request, a protocol stall is used, but uniquely with control transfer.
1. The microcontroller sets the FORCESTALL flag in the UDP_CSRx endpoint’s register.
2. The host receives the stall packet.
Chapter 9 of the Universal Serial Bus Specification, Rev 2.0, for more information on the halt
feature.)
