* Selecting a port for analog input does NOT default all pins of that port as analog input. After select-
ing a port for analog input, a pin must be selected using pin select bits (PINSL2–0). For example,
after setting the AMXEN to ‘1’, setting PRTSL1–0 to “11”, and setting PINSL2–0 to “100” P3.4 is
configured as analog input. All other Port 3 pins remain as GPIO pins. Also note that in order to use
a port pin as analog input, its input mode should be set to analog . Please see section 14.2.
