9.1.1.2GPIO Pin Direction Register (GPDR)

Pin direction is controlled by programming the GPIO pin direction register (GPDR). The GPDR contains one direction control bit for each of the 28 port pins. If a direction bit is programmed to a one, the port is an output. If it is programmed to a zero, it is an input. At hardware reset, all bits in this register are cleared, configuring all GPIO pins as inputs. Soft resets and sleep reset have no effect on this register. For reserved bits, writes are ignored and reads return zero. The following table shows the location of each pin direction bit in the GPIO pin direction register.
