To use these MUXed pins as GPIO signals, the appropriate GPIO register bits (GPxEN and GPxDIR) must be properly 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 or GPIO as input-only. ‡ RSV EMU11 RSV RSV RSV • • • Peripheral Control/Status PCI_EN MCBSP2_EN For the C6415 and C6416 devices, these GPIO pins are MUXed with the PCI peripheral pins. By default, these signals are set up to no function with both the GPIO and PCI pin functions disabled. For more details on these MUXed pins, see the Device Configurations section of this data sheet. For the C6414 device, the GPIO peripheral pins are not MUXed; the C6414 device does not support the PCI peripheral. § Figure 2. CPU and Peripheral Signals |
