I'm working on a ultra-low power application and want to enable and access only one pin as output and one pin as input. I'm using the MSP430 microcontroller and CCS for programming. I have two questions.
The MSP430 allows accessibility of a whole port. Is it possible to access only the required two pins as input and output (which is possible in PIC)?
Doesn't accessing (and enabling) the whole port (8 pins) consume more current compared to accessing (and enabling) a single pin?
