  7. 4Revision History

GPIO Pin Mapping

The developer can enable GPIO pins individually, as needed, as output, input, or both. Most of the LVCMOS pins not currently allocated for other peripheral use can be defined as GPIO pins. Table 2-5 is a compliment to the schematic and the recommended settings in the pinmux tool. Each of the defined GPIO pins are listed along with the associated pin name and ball number and mode. The last column lists the available physical pull-up (PU) or pull-down (PD) resistor attached or the recommended internal pull-up or pull-down resistor defined in the pinmux file provided for the AM572x IDK EVM.
