Hello,
In the Hitex lpc4350 evaluation board, I have noticed that USB 0 section of LPC controller has signals like USB0_VBUS, USB0_RREF, USB0_VDDA_3V3_DRIVER, USB0_VDDA3V3, USB0_VSSA_TERM, USB0_VSSA_REF , while USB1 doesnt have these extra signals.
What will be the effect if these signals are absent for USB0 i.e. I dont connect these pins at all, leave them open. How it will affect my circuit. I am studying the circuitry on the board, so I would like to know what happens when some signals are missing.
Please help me with this.
Thanks and Regards,
Sooraj.
