3.5 GPIO table
3.5.1 Alternate Function
Table below shows available GPIO pins can be set into different function,customer can choose related
function according to the table. Before implementing them into real design, need to confirm with WNC.
I：input IO pad. O：output IO pad. B: bidirectional IO pad(Input and output).
