Table 3-2, “USB251xB/xBi Pin

Descriptions,” on page 12

Updated VBUS_DET buffer type to “I” and changed

description to: “For self-powered applications with a

permanently attached host, this pin must be

connected to a dedicated host control output, or

connected to the 3.3 V domain that powers the

host (typically VDD33).”
