I am trying to use CY8C24894 in a design including the USB interface. I want to use it as a self-powered device.
I read several files on it but one thing is not clear. Do I need to provide an external pull-up resistor to D+ or is that handled by the USBFS module. The supply voltage for my PSoC1 device is 5V.

In this ap note http://www.cypress.com/?rID=12956 referenced in the
module datasheet, it shows the R as external.
