The GPIO0–7 pins have configurable assignments. There are 4 possible functional
pin out configurations. These 4 configurations are called Port Config 0–3. In each
Port Configuration each GPIO is defined as a specific functional pin. The GPIO pin
assignment can be seen in Table 3-14 . ME906s supports Config 0. But the audio
function is not implemented in ME906s.
