3.0 General-Purpose Input/Output (GPIO) Port
3.4.2
This is a group of eight identical configuration registers, each of which is associated with one GPIO pin. The entire set is
mapped to the PnP configuration space. The mapping scheme is based on the GPSEL register that functions as an index
register, and the specific GPER register that reflects the routing configuration of the currently selected pin. For details on the
GPSEL register, refer to the Device Architecture and Configuration chapter.
This set of registers is applicable only for the enhanced GPIO port with event detection support. In the basic port this register
set is reserved, returns 0 on read and has no effect on port functionality.
