8.5.1 Pin Function Select register 0 (PINSEL0 - 0x4002 C000)
The PINSEL0 register controls the functions of the lower half of Port 0. The direction
control bit in FIO0DIR register is effective only when the GPIO function is selected for a
pin. For other functions, the direction is controlled automatically.
[1] Not available on 80-pin package.
8.5.2 Pin Function Select Register 1 (PINSEL1 - 0x4002 C004)
The PINSEL1 register controls the functions of the upper half of Port 0. The direction
control bit in the FIO0DIR register is effective only when the GPIO function is selected for
a pin. For other functions the direction is controlled automatically.
