P4.6 is not set to input floating if device is in RESET state
P4.6 is driven active low while the MSP430 device is held in a reset state. This can influence components connected externally that are expecting the pin to act as a floating input during MSP430 reset.
Use any other GPIO if input floating state is required while the device is in a reset state.
