The background to my question is that I am trying to specify connections that will be compatible across a range of products.
Suppose the 1.8V USB power supply is not provided on my board and none of the USB power pins (USB0_VDDA33, USB0_VDDA18) are connected and there is no filter capacitor on USB0_VDDA12. Is it nevertheless permissible to connect USB0_VBUS to +5V, USB0_DRVVBUS through a 1.5K pullup to +3.3V, and USB0_ID to ground? Or must some or all of these pins be left unconnected?
(BTW when I enter the part number TMS320C6747 it forces the "Select a forum" dropdown to be "C64x Single Core DSP Forum", and that is not correct!" I checked "I don't have a part number" so this post could show up in the correct forum.)
