I'm reading and checking a Layout I've made for a Board cause I have trouble with USB Connection. In The ATmel Notes http://www.atmel.com/Images/Atmel-42187 ... T03462.pdf I found:
Okey... I'm not Native English, but I understand much and this is over my top...2.9 USB OTG HS
The UOTGVBOF and UOTGID pins are multiplexed with I/O Controller lines and may also be multiplexed with lines of other peripherals. In order to use them with the USB, the user must first configure the I/O Controller to assign them to their USB peripheral functions.
a. If UOTGID is used, the I/O Controller must be configured to enable the internal pull-up resistor of its pin.
b. If UOTGVBOF or UOTGID is not used by the application, the corresponding pin can be used for other purposes by the I/O Controller or by other peripherals.
I have PB11 connected to USBid with Varistor (CG0603MLC-05E 5V 0,5pf 50nA) tied to Ground and D+/D- with Varistor to gnd and DHSDP/DHSDM. With 39R1% they are connected to the right DFSD* Pin.
My problem is understanding "configure I/O Controller". Does it mean Erase Chip and Reset to load Sam-ba to Flash or do I first have to plug something by JTAG or so to set the right fuses/bits/whatever?
Help me solving my confusion is very much appreciated.
