7.4.3 Pin function select register values
The PINSEL registers control the functions of device pins as shown below. Pairs of bits in
these registers correspond to specific device pins.
The direction control bit in the IO0DIR register is effective only when the GPIO function is
selected for a pin. For other functions, direction is controlled automatically. Each derivative
typically has a different pinout and therefore a different set of functions possible for each
pin. Details for a specific derivative may be found in the appropriate data sheet.
