General-Purpose Input/Output (GPIO) Port?These pins are muxed with the GPIO port pins and by default these signals function as clocks (CLKOUT4 or CLKOUT6) or McBSP2clock source (CLKS2). To use these muxed pins as GPIO signals, the appropriate GPIO register bits (GPxEN and GPxDIR) must beproperly enabled and configured. For more details, see the Device Configurations section of this data sheet.
?These pins are GPIO pins that can also function as external interrupt sources (EXT_INT[7:4]). Default after reset is EXT_INTx orGPIO as input-only.
§For the C6415 and C6416 devices, these GPIO pins are muxed with the PCI peripheral pins. By default, these signals are set up tono function with both the GPIO and PCI pin functions disabled. For more details on these muxed pins, see the Device Configurationssection of this data sheet. For the C6414 device, the GPIO peripheral pins are not muxed; the C6414 device does not support thePCI peripheral.
