Table 5-3 Jumper Descriptions
JumperDescriptionDefault Position
JP1Ties PWR_EN to VIO or GNDPWR_EN tied to VIO
JP2Ties DC34_SEL pin to ground. Remove and jump with resistor for alternate voltage selections.DC34_SEL tied to GND
JP3Selects LS1 input between DCDC3 output and external supply from J1IN_LS1 tied to DC3
JP4Ties VIO to either DCDC4 output or 3.3-V supply from USB2ANY adaptor (J9). VIO supplies the pull-up voltage for the device I/Os.VIO tied to V3p3
JP5Ties AC_DET pin to either VSYS or GND. Tying to GND causes the device to start upon VSYS application.AC_DET tied to VSYS
