AINCOM/DAC
I/O
All analog inputs can be referred to this pin, provided that a relevant pseudo
differential input mode is selected. This pin also functions as an alternative pin
out for the DAC.

P3.0–P3
I/O
P3.0 to P3.7 are bidirectional port pins with internal pull-up resistors. P
pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 3 pins being
pulled externally low source current because of the internal pull-up resistors
When driving a 0-to-1 output transition, a strong pull-up is active for one cor
clock period of the instruction cycle.
Port 3 pins also have the various secondary functions described below.
