GPIO
WADE-8065 provides 8 programmable input or output ports that can be individually
configured to perform a simple basic I/O function. Users can configure each
individual port to become an input or output port by programming register bit of I/O
Selection. To invert port value, the setting of Inversion Register has to be made. Port
values can be set to read or write through Data Register.
