Figure 24-147 shows a typical application using the SuperSpeed USB subsystem. The application represents a full-featured integration and allows all of the capabilities of the controller used.
VBUS sensing can be exported to the external Power-Management IC (PMIC) in case it supports this function. This would eliminate the need for additional components such as level shifters and comparators. In this case, software driver must be modified to be able to react on PMIC interrupts for VBUS-rise and VBUS-fall through the I2C1 interface.
Some PMICs support the VBUS_DETECT output from the VBUS comparator to be muxed directly on their GPIO pin. In this case PMIC VBUS_DETECT can be connected to a SoC GPIO pin, thus, this functionally is identical to Figure 24-147.
See the respective PMIC datasheet for details.
