16.10.3.Endpoint0 OUT Transactions
When a SETUP request is received that requires the host to transmit data to USB0, one or more OUT
requests will be sent by the host. When an OUT packet is successfully received by USB0, hardware will set
the OPRDY bit (E0CSR.0) to ‘1’ and generate an Endpoint0 interrupt. Following this interrupt, firmware
should unload the OUT packet from the Endpoint0 FIFO and set the SOPRDY bit (E0CSR.6) to ‘1’.
If the amount of data required for the transfer exceeds the maximum packet size for Endpoint0, the data
will be split into multiple packets. If the requested data is an integer multiple of the maximum packet size
for Endpoint0 (as reported to the host), the host will send a zero-length data packet signaling the end of the
transfer.
Upon reception of the first OUT token for a particular control transfer, Endpoint0 is said to be in Receive
Mode. In this mode, only OUT tokens should be sent by the host to Endpoint0. The SUEND bit (E0CSR.4)
is set to ‘1’ if a SETUP or IN token is received while Endpoint0 is in Receive Mode.
Endpoint0 will remain in Receive mode until:
Firmware should set the DATAEND bit (E0CSR.3) to ‘1’ when the expected amount of data has been
received. The SIE will transmit a STALL condition if the host sends an OUT packet after the DATAEND bit
has been set by firmware. An interrupt will be generated with the STSTL bit (E0CSR.2) set to ‘1’ after the
STALL is transmitted.

1. The SIE receives a SETUP or IN token.
2. The host sends a packet less than the maximum Endpoint0 packet size.
3. The host sends a zero-length packet.
