Hardware Design Considerations
3.6.4.1
This figure shows the required divider network for the VBUS interface for the chip. Additional requirements for the external
components are as follows:
USB1_DRVVBUS and USB1_PWRFAULT are muxed on GPIO[4:5] pins, respectively. USB2_DRVVBUS and
USB2_PWRFAULT are muxed on GPIO[6:7] pins, respectively. Setting the RCW[GPIO] bit selects USB functionality on the
GPIO pins.
