Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
Serial Data 1 — This pin serves as the I²C serial data line.
CAN Receive Data — This is the MSCAN interface input.
After reset, the default state is GPIOB9. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.
25_{The SDA signal is also brought out on the GPIOB1 and GPIOB6 pins.}
26_{The CANRX signal is also brought out on the GPIOB13 pin.}
