6.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than
one function. Configuration registers control the multiplexers to allow connection
between the pin and the on chip peripherals. Peripherals should be connected to the
appropriate pins prior to being activated, and prior to any related interrupt(s) being
enabled. Activity of any enabled peripheral function that is not mapped to a related
pin should be considered undefined.
The Pin Control Module contains two registers as shown in Table 5.

6.7 Pin function select register 0 (PINSEL0 - 0xE002C000)
The PINSEL0 register controls the functions of the pins as per the settings listed in
Table 6. 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 Table 6 are reserved, and should not be used
