R0SEQ — Endpoint 0 Receive Sequence Bit
This read-only bit indicates the type of data packet last received for
endpoint 0 (DATA0 or DATA1).
1 = DATA1 token received in last endpoint 0 receive
0 = DATA0 token received in last endpoint 0 receive
SETUP — SETUP Token Detect Bit
This read-only bit indicates that a valid SETUP token has been
received.
1 = Last token received for endpoint 0 was a SETUP token
0 = Last token received for endpoint 0 was not a SETUP token
RP0SIZ3–RP0SIZ0 — Endpoint 0 Receive Data Packet Size
These read-only bits store the number of data bytes received for the
last OUT or SETUP transaction for endpoint 0.
