This bit will be compared with the type of data packet last received for
Endpoint0
SETUP Token Detect Bit. This bit is set when the received token packet
is a SEPUP token, PID = b1101.
IN Token Detect Bit.
This bit is set when the received token packet is an IN token.
OUT Token Detect Bit.
This bit is set when the received token packet is an OUT token.
