Which MSP are you using? There are >400 different MSPs, and pin mappings are device specific. From the usage of UCB0 and IE2 and P1SEL2, I see it must be a 2x family device, but beyond that I can only guess it might be a G2553. If so, then perhaps the 20 pin PDIP version for the LaunchPad. If so, then UCB0CLK is available on P1.5 (not P1.4) and there is no way to redirect it to P2.2 (except connecting the two pins externally J )
Only the 5x/6x family devices have port mapping capabilities, and even those are limited.
