Note:
For -B02 models only: Pins 14, 15, 16, and 27 are part of the SPI interface. These pins are inputs. If you do
not use them, connect them externally to a high level signal (preferably through a high pull up resistor) to keep
them from floating.

MTQ-EV3-B01 External Pin Alternate Function Mapping
This table shows alternate functions available on the external pins of the -B01 models. These functions are
available in mbed and can be redefined by the user. This table also shows which I/O pins are mapped to specific
Arduino shield pins on the MTUDK2-ST-CELL developer board.
Note:
For readability, this table has been split into two parts.
