Comments
Ignore all USB traffic to this endpoint
On Control endpoint, after successfully sending an ACK
handshake to a SETUP packet, the SIE forces the
endpoint mode (from modes other than 0000) to 0001.
The mode is also changed by the SIE to 0001 from mode
1011 on issuance of ACK handshake to an OUT.

In mode 1001, after sending an ACK handshake to an
OUT, the SIE changes the mode to 1000
This mode is changed by the SIE to mode 1000 on
issuance of ACK handshake to an OUT
This mode is changed by the SIE to mode 0001 on
issuance of ACK handshake to an OUT
An ACK from mode 1101 changes the mode to 1100
This mode is changed by the SIE to mode 1100 on
issuance of ACK handshake to an IN
An ACK from mode 1111 changes the mode to 1110
This mode is changed by the SIE to mode 1110 on
issuance of ACK handshake to an IN
