Hello @qinweiliang 

I suggest you to take a look at the schematic pack of your board revision C01 or C02. They are both available here. Also, more details can be found about the state of those solder bridges SB (on if they are fitted or off if not) on the table 12 of the UM2206.
PS: default state is always in bold.

Best Regards.

The detailed information on what is connected may be found in board's User Manual.
