After the SoC has entered the Deep Sleep mode, USB1 can be used to wakeup the SoC based on USB events triggered by USB devices. This requires that the pin corresponding to the Type-A connector remains pulled up even after the SoC has entered the Deep Sleep mode. Hence, enable Deep Sleep pullup / pulldown selection for the USB1_DRVBUS pin and set its Deep Sleep state to PULL_UP.
