P1.0/AIN1
I
By power-on default, P1.0/AIN1 is configured as the AIN1 analog input.
AIN1 can be used as a pseudo differential input when used with AINCOM or as
the positive input of a fully differential pair when used with AIN2.
P1.0 has no digital output driver. It can function as a digital input for which 0
must be written to the port bit. As a digital input, this pin must be driven high
or low externally.

1
P1.1/AIN2
I
On power-on default, P1.1/AIN2 is configured as the AIN2 analog input.
AIN2 can be used as a pseudo differential input when used with AINCOM or as
the negative input of a fully differential pair when used with AIN1.
P1.1 has no digital output driver. It can function as a digital input for which 0
must be written to the port bit. As a digital input, this pin must be driven high
or low externally.

2
P1.2/AIN3/REFIN2+
I
On power-on default, P1.2/AIN3 is configured as the AIN3 analog input.
AIN3 can be used as a pseudo differential input when used with AINCOM or as
the positive input of a fully differential pair when used with AIN4.
P1.2 has no digital output driver. It can function as a digital input for which 0
must be written to the port bit. As a digital input, this pin must be driven high
or low externally. This pin also functions as a second external differential
reference input, positive terminal.

3
P1.3/AIN4/REFIN2
I
On power-on default, P1.3/AIN4 is configured as the AIN4 analog input.
AIN4 can be used as a pseudo differential input when used with AINCOM or as
the negative input of a fully differential pair when used with AIN3.
P1.3 has no digital output driver. It can function as a digital input for which 0
must be written to the port bit. As a digital input, this pin must be driven high
or low externally. This pin also functions as a second external differential
reference input, negative terminal.
