Explanation of Terms
• SE0: USB data transfer uses a D+/D– differential signal. Consequently, D+/D– is normally a
reciprocal signal. However, in some special cases D+ and D– are both defined as low. This
state is referred to as SE0.
• Device not connected detection: Detection of a USB device not connected state when SE0
continues beyond the device not connected detection duration.
