USB Interface
USB Type-C receptacle x 1 is equipped with RTK7921053C00000BE as a default installation.
When using this receptacle as a USB host, attach JP3 because the VBUS voltage is supplied to the USB connector.
When using this receptacle as a USB function, detach JP3.
Moreover, USB port setting can be changed by the CC logic controller (U7) PORT terminal settings. Initial USB port
settings are for DRP (Dual Role Port). If using as a USB host, mount R78 resistor and set USB port to DFP (Downstream
Facing Port). If using for USB function, mount R79 resistor and set USB port to UFP (Upstream Facing Port).
Figure 2.4.1 shows USB interface block diagram, Table 2.4.1 shows jumper JP3 function setting table, Table 2.4.2
shows port L function switching table, and Table 2.4.3 shows USB port function switching table.
