SPRUIM6A October 2018 – November 2020
The SoC supports two USB 2.0 ports – USB0 and USB1. The USB0 port is routed to the SERDES daughter card connector along with USB0 ID pins and DRVVBUS0 for host / slave detect and power enable. The USB1 port is terminated to a uAB connector (J3) and supports both host and slave mode. In the host mode, up to 500 mA, 5 V is supported for the slave device. A power switch is included which is controlled by DRV_VBUS signal from the AM65x processor. A 2x3 header (J4) is provided to install the 2-position ganged shunt to configure the port for host mode, as shown in Figure 3-19. Place the shunt on pin 1 and 2 to enable bulk capacitance on VBUS, and place the shunt on pin 5 and 6 to connect ID pin to ground.
