Signal Description
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
SS — SS is used in slave mode to indicate to the SPI module that
the current transfer is to be received.
(SDA)
Input/Open
-drain
Output
SDA — The I²C serial data line.
(ANA12 and
CMP2_P3)
Analog
input
ANA12 and CMP2_P3 — Analog input to channel 12 of ADCA and
Positive input 3 of analog comparator 2.
When used as an analog input, the signal goes to the ANA12 and
CMP2_P3.

After reset, the default state is GPIOB1.
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
MISO — Master in/slave out. In master mode, this pin serves as the
data input. In slave mode, this pin serves as the data output. The
MISO line of a slave device is placed in the high-impedance state if
the slave device is not selected.
(TIN2)
Input/
Output
TIN2 — Dual timer module channel 2 input.
(ANA2 and
ANB2)
(CMP0_

Analog
Input
Output
ANA2 and ANB2 — Analog input to channel 2 of ADCA and ADCB.
CMP0_OUT— Analog comparator 0 output.
When used as an analog input, the signal goes to the ANA2 and
ANB2.
After reset, the default state is GPIOB2.
