Po-kai,
The obligatory first question: instead of using pins A6 and A8 ("A"
for "10-pin header", "B" for "6-pin header"), is there a reason you
can't use pins A7 or A10 (GIO0, GIO1) or pins B3 or B4 (GIO2, GIO3)?
Also, you only need the GIO (MSP430 P2) lines if you want to receive
interrupts on the MSP430. If you only need digital IO without
interrupt capability, you can also use pins A2, A3, A4, A5, B1, and
B2.
Best,
Cory
