The figure below shows the pinouts of Motor 2 c Arduino socket connectors. Odd pins (inner side pins) of the socket are
used for motor control. Even pins (outer side pins) of the socket provide connection with an external Arduino board.

2.14 GPIOs and interrupts
The table below lists the target MCU pins that are used as general-purpose inputs/outputs (GPIOs) on the LPC55S36-EVK board.
Some of these pins are also used for other purposes on the board.
