Well, just lookup the schematics to which port the pin you want to
control is connected, then look in the datasheet how to control the
GPIO. You must make sure the port you want to control is in gpio mode in
port_config register, then setup it as output and drive a value onto it
... There is nothing currently in place to do that easily from userspace ...
