AT43USB353M
3307B–USB–4/04
The following information describes how the AT43USB355’s USB hardware and firmware
operates during a control transfer between the host and the hub’s or function’s control end-
point.
Idle State
This is the default state from power-up.
Setup Response State
The Function Interface Unit (FIU) receives a SETUP token with 8 bytes of data from the Host.
The FIU stores the data in the FIFO, sends an ACK back to the host and asserts an
RX_SETUP interrupt.
Legend:
DATA1/DATA0 = DATA packet with DATA1 or DATA2 PID
DATA1(0) = Zero length DATA1 packet

b. If Control Write: clear DIR in CAR0
c. If no Data Stage: set Data End, clear
DIR, set Force STALL in CAR0
