AT^SPIO General Purpose IO Driver Open/Close
Syntax
Command Description
The write command opens and closes the general purpose IO driver. It must be executed before any other gen-
eral purpose IO pin commands can be used. After closing the driver, all pins used (i.e. opened) will be put into
high impedance state (inputs) with no internal pull up or down.
The command does not reserve any general purpose IO pin, only the drivers required for GPIO pin management
will be loaded.
