Hi,
According to the datasheet I must supply 3.3V to VDDUSB when USB is in use, but my question is - Can I connect 3.3V LDO directly to VBUS, so that when USB is not present - USBVDD pin is 0V.
Its is unclear whether this works from the datasheet. In one place it says I can have 0V there, in other - that I MUST connect it to VDD
Thanks,
Tim
