Write:
This read-only bit indicates the type of data packet last received for
endpoint 2 (DATA0 or DATA1).
This read-only bit indicates that an ACK token has been transmitted.
This bit is updated at the end of the data transmission.
This read-only bit indicates that a TXNAK token has been transmitted.
This bit is updated at the end of the data transmission.
This read-only bit indicates that a STALL token has been transmitted.
This bit is updated at the end of the data transmission.
These read-only bits store the number of data bytes received for the
last OUT transaction for endpoint 2.
1 = DATA1 token received in last endpoint 2 receive
0 = DATA0 token received in last endpoint 2 receive
1 = Last token transmitted for endpoint 0 was an ACK token
0 = Last token transmitted for endpoint 0 was not an ACK token
1 = Last token transmitted for endpoint 0 was a NAK token
0 = Last token transmitted for endpoint 0 was not a NAK token
1 = Last token transmitted for endpoint 0 was a STALL token
0 = Last token transmitted for endpoint 0 was not a STALL token
