Signal Descriptions
Freescale Semiconductor

4.2
GPIO
Many pins have an optional GPIO function.
General purpose input is always active, regardless of state of pin.
General purpose output or primary output is determined by the appropriate setting of the Pin
Multiplex Control Registers, GPIO-FUNCTION, GPIO1-FUNCTION and PIN-CONFIG.
At Power-on reset, all pins are set to their primary function.
