Received Data Toggle Bit
This bit indicates the toggle bit of the received data packet:
0 = Data0, and
1 = Data1
SETUP Token Detect Bit
This bit is set when Endpoint0 receives a SETUP token. This
bit is not cleared when Endpoint0 receives an IN or OUT token
following the SETUP token that set this bit. This bit is cleared
by software or a reset.
IN Token Detect Bit
This bit is set when Endpoint0 receives an IN token. This bit is
cleared when Endpoint0 receives a SETUP or OUT token.
OUT Token Detect Bit
This bit is set when Endpoint0 receives an OUT token. This bit
is cleared when Endpoint0 receives a SETUP or IN token.
