Remark
JP1
Pin 1 = PI5PD2068 output
Pin 2 = Vbus pin of USB
receptacle connector
Pin 1 = PI5PD2069 output
Pin 2 = Vbus pin of USB
receptacle connector
Short = connect the +5V output to
USB receptacle connector
JP4 Pin 1 = Vbus from USB plug
Pin 2 = VDD of PI5USB1458
Pin 1 = Vbus from USB plug
Pin 2 = VDD of PI5USB1458A
Short =EVB power up by Vbus of
USB plug
Open = EVB need to power up by
external power supply
JP5 Pin 1 = 10kohm to +5V
Pin 2 = SEL of PI5USB1458
