D+/D- low for an extended period
A device may reset after seeing an SE0 for more than 18.7 uS, and definitely after 10mS.
After power up and prior to Reset, the device will not respond to any USB commands. After the
device has been given a USB Reset, the device’s address will be reset to zero and the device will
be in the Default state. The chip will default to Report protocol and any pending output will be
flushed.
All registers will be reset to a state that matches power-on-reset with the following exceptions:
USB State register will be “Default” instead of “Attached”.
Idle state for an extended period
A device may suspend after seeing an idle for more than 3mS, and definitely after 10mS.
The chip will take a minimum of 5mS to start Suspend, though will definitely start after 6mS.
The chip may finish the current frame if necessary before stopping the clock. Thus, an additional
frame time may be used to reach Suspend mode.
Non-idle state
Remote Resume signalling from a device must be between 1mS and 15mS. The host is required
to send Resume signaling for 20mS plus 10mS of resume recovery time in which it does not
access any devices. This allows devices enough time to wake back up.
The chip can cause a Resume if Remote Wakeup is enabled and a button has been pressed.
Remote resume signalling from the chip will last 11.45mS to 12.45mS.
