Hey Shu-Cheng,
Everything on our device looks good. The device address is correct at 0x70h.
1) Just to be sure you have pull up resistors tied to SDA/SCL_BL(1,2,3,4).
2) INT0,1,2,3 are okay to have one pull up resistor.
3) The 10uF caps are a bit of an overkill. You don't need that much. It should still work though.
Thanks,
-Bobby
