In the reference manual of ADSP-BF548 EZ-KIT LITE , I have certain queries in the circuit of USB.

 

Please refer to Pg 120 of the attached manual.In this it has been mentioned that Pins 1&3 and pins 2&4 of jumper JP11 should always be populated. May I know what is the purpose of this jumper.

By using this jumper , we are supplying power to USB module of DSP , which can directly be given using 3.3V , then what is the need of generating 3.6V
