I am using BF548 processor in our project, but i am not using USB controller in this DSP, in the datasheet it is mentioned that pull low/high lines when not used.


1. Do i have to use any resistor value to pull-up or pull-down these pins or can i short them directly to voltage or ground?

2. Also specify whether voltage should 3.3V or 5V?
