All general purpose IO (GPIO) is programmable by the user. Some GPIO has alternate
functionality already associated with it; this is indicated in the default column. GPIO
which has alternate function is effectively multiplexed, so that the user chooses
through AT commands the appropriate configuration for their application.
GPIO is programmable for the following features:
• An input or output
• Level-sensitive or transition-sensitive
