6.7 Pin function select register 1 (PINSEL1 - 0xE002 C004)
The PINSEL1 register controls the functions of the pins as per the settings listed in
Table 8. The direction control bit in the IODIR register is effective only when the GPIO
function is selected for a pin. For other functions direction is controlled automatically.
Settings other than those shown in the Table 8 are reserved, and should not be used.
