USB_DN_DOWN signal
J14 – Determines whether USBDP is pulled down directly or controlled by
USB_DP_DOWN signal
A jumper across 1 & 2 pulls down USBDN directly.
A jumper across 2 & 3 indicates that the USB_DN_DOWN signal controls the
pull down of USBDN signal. This is the default setting.
A jumper across 1 & 2 pulls down USBDP directly.
