P1.2-P1.7
I
Port 1.2 to Port 1.7 have no digital output driver; they can function as a digital
input for which ‘0’ must be written to the port bit. As a digital input, these pins
must be driven high or low externally.
T hese pins also have the following analog functionality:
T he voltage output from the DAC or one or both current sources (200 μA or 2 x
200 μA) can be configured to appear at this pin.
Auxiliary ADC Input or one or both current sources can be configured at this pin.
Primary ADC, Positive Analog Input
Primary ADC, Negative Analog Input
Auxiliary ADC Input or muxed Primary ADC, Positive Analog Input
Auxiliary ADC Input or muxed Primary ADC, Negative Analog Input. T he voltage
output from the DAC can also be configured to appear at this pin.

P3.0–P3.7
I/O
P3.0–P3.7 are bidirectional port pins with internal pull-up resistors. Port 3 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 will source current because of the internal pull-up resistors. When driving a
0-to-1 output transition, a strong pull-up is active for two core clock periods of
the instruction cycle.
Port 3 pins also have various secondary functions described below.
