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 - 0xE002 C000)

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
