15. 15. POWER jumper
    • VBAT: short the jumper to use system power supply, open it to connect external power, such as battery
    • VREF: short the jumper to connect VREF+ to VCC, open it to connect VREF+ to other custom pin via jumper wire
16. 16. OTG jumper
    • short the jumper when using USB OTG/HOST
    • open the jumper to disconnect from related I/O port

Note: CoreH743I provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
