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 three 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
