All 16 GPIO pins come from W83627THG, Winbond. GP10~GP17, GP20~GP26 and
GP30 of W83627THG are connected to J12 and J15. GP10~GP17 are CMOS level
Schmitt-triggered bi-directional pins and open-drain outputs with 12 mA sink
capability. GP20~GP26 and GP20 are TTL level Schmitt-triggered bi-directional pins
and open-drain outputs with 12 mA sink capability.
Users can refer to W83627THG, Winbond datasheet to 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.
