VBUS Charge Pump (USB OTG Supply)
With the pin USBH_CSN and USBH_CSP connected to ground the USB-OTG mode is selected. In this mode the charge pump supplies
5V and 8mA. The charge pump uses the QLDO2 voltage as input and doubles its voltage with the help of the flying capacitor between
CP_CP and CN_GEXT to its output VBUS. If the pulse skip bit is set in the related register, the charge pump switches to pulse skip mode
for improved efficiency. Enabled pulse skip mode, however, compromises with a higher output voltage ripple.
