Pin Assignments[4] (continued) Pin CY7C65631 Name CY7C65621 Name Type Default Description Note 4. Unused port DD+/DD– lines can be left floating. Leave the port power, amber, and green LED pins unconnected, and deassert the overcurrent pin. Do not leave the overcurrent pin floating; it is an input. [+] Feedback |
