[13:12]
Fully programmable GPIOs that can be used for a variety of dedicated or specific functions. GPIO[7:3] pins
default as inputs. They are programmable to function as GPI[7:3] inputs, GPO[7:3] outputs, ALF[7:3]
outputs, or ID[7:3] inputs. In addition, if this pin is configured as output, TTL output, Open Drain or Open
collector can be selected. Refer to GPIO Config.1&2 Registers for more details and GPIO Config. Tables
(section 8) for input/output selections.
