This read only bit indicates the type of data packet last received for Endpoint 0
(DATA0 or DATA1).
This read only bit indicates that a valid SETUP token has been received.
These read only bits store the number of data bytes received for the last OUT
or SETUP transaction for Endpoint 0. These bits are not affected by reset.
These read only bits are serially loaded with OUT token or SETUP token data
received over the USB’s D+ and D– pins.
These write only buffers are loaded by software with data to be sent on the
USB bus on the next IN token directed at Endpoint 0.

reset:
1 = DATA1 Token received in last Endpoint 0 receive
0 = DATA0 Token received in last Endpoint 0 receive
1 = Last token received for Endpoint 0 was a SETUP token
0 = Last token received for Endpoint 0 was not a SETUP token
