Control Read Status
Response State
The Function Interface Unit receives an OUT token from the Host with a zero length DATA1
packet. The FIU responds with a NAK until TX_COMPLETE is cleared. The FIU will then ACK
the retried OUT token from the Host and assert an RX_OUT interrupt.
Control Write Data
Response State
The Function Interface Unit receives an OUT token from the Host with a DATA packet. The
FIU places the incoming data into the FIFO, issues an ACK to the host, and asserts an
RX_OUT interrupt.

1.
OUT token from Host
2.
DATA1(0) from Host
3.
TX Complete = 0
a. If yes, ACK to Host
Set RX OUT
→
INT
b. If no, NAK to Host
4.
Read UISR
5.
Read CSR0
6.
Clear RX OUT, set Data End, set
Force Stall in H/FCAR0.
Note: A SETUP token will clear Data
End, therefore, it is not cleared by
FW in case Host retries.
Set UIAR[EP0 INTACK] to clear
interrupt source
