3.3 GPIO OUT

Those GPIO bits which were configured as outputs are configured when writing to this address. Note that writing to this address is equivalent to writing to the MSP430 PxOUT register so only bits which are configured to be outputs on their respective PxDIR register, will react accordingly. Those pins which are configured as inputs will still behave as inputs.
