The firmware has to change the Token for each phase.
The initial data toggle is set for the corresponding token (ONLY for Control Pipe):
• SETUP: Data0
• OUT: Data1
• IN: Data1 (expected data toggle)
OUT Pipe Management The Pipe must be configured and not frozen first.
Note: if the firmware decides to switch to suspend mode (clear SOFE) even if a bank is
ready to be sent, the USB controller will automatically exit from Suspend mode and the
bank will be sent.
