Part Number: TMS320F28069
Tool/software: Code Composer Studio
I am designing my own 28069 pcb board, aiming for sensor data transfer to PC via USB bulk transmission.
Do I need to pull DP high?
I thought DP should be pulled high internally in MCU, but in the program, after USBIOEN enabled, both DP DM are pulled low, is it correct?
Or maybe the voltage level will be OK after the USB initialization?
I am not sure what is the correct behaviour.
