DRSEQ — Embedded Device Endpoint 0 Receive Sequence Bit
DSETUP — Embedded Device SETUP Token Detect Bit
DTX1ST — Embedded Device Transmit First Flag
DTX1STR — Clear Transmit First Flag
RP0SIZ3-RP0SIZ0 — Embedded Device Endpoint 0 Receive Data
Packet Size
This read only bit indicates the type of data packet last received for
embedded device Endpoint 0 (DATA0 or DATA1).
This read only bit indicates that a valid SETUP token has been
received.
This read only bit is set if the embedded device Endpoint 0 Data
Transmit Flag (TXD0F) is set when the USB control logic is setting the
embedded device Endpoint 0 Data Receive Flag (RXD0F). In other
words, if an unserviced Endpoint 0 Transmit Flag is still set at the end
of an endpoint 0 reception, then this bit will be set. This bit lets the
firmware know that the Endpoint 0 transmission happened before the
Endpoint 0 reception. Reset clears this bit.
Writing a logic 1 to this write only bit will clear the DTX1ST bit if it is
set. Writing a logic 0 to the DTX1STR has no effect. Reset clears this
bit.
These read only bits store the number of data bytes received for the
last OUT or SETUP transaction for embedded device Endpoint 0.
These bits are not affected by reset.
1 = DATA1 Token received in last embedded device Endpoint 0
0 = DATA0 Token received in last embedded device Endpoint 0
1 = Last token received for Endpoint 0 was a SETUP token
0 = Last token received for Endpoint 0 was not a SETUP token
1 = IN transaction occurred before SETUP/OUT
0 = IN transaction occurred after SETUP/OUT
