The GPIO Direction Register controls the direction of GPIOs 1 and 2.
Bit 1 - GPIO2_DIR - Determines the direction of GPIO2.
Bit 0 - GPIO2_DIR - Determines the direction of GPIO1.
The GPIO Output Configuration Register controls the output pin type of each GPIO pin.
Bit 1 - GPIO2_OT - Determines the output type for GPIO2.
Bit 0 - GPIO1_OT - Determines the output type for GPIO1.
