hi, does anyone know what is the function of USB_RSET and USB_VREF pin in BF526 USB, how to connect these pins? thanks!
I have recieved information from ADI .
USB_VREF This pin should be coupled to GND. This is a pin used to calibrate our USB analog PHY and thus has no role in normal operation.
This pin should be left Floating . This was provided for future upgrades ...... you could use a Do not populate resistor to Ground also .
With best regards
i would like to ask, if the USB controller still works(in host mode) even if the pin USB_VREF is not connected to ground (it is left unconnected).Thanks!
Operation of the USB controller cannot be guaranteed if USB_VREF is left floating. The datasheet recomends that this pin be tied to ground through a decoupling capacitor.
Retrieving data ...
