For the C6415 and C6416 devices, all other standalone UTOPIA and PCI pins are tied-off internally (pins in Hi-Z) when the peripheral is disabled
[UTOPIA_EN (BEA11) = 0 or PCI_EN = 0].
The C6414 device does not support the PCI and UTOPIA peripherals. These are the only multiplexed pins on the C6414 device, all other pins
are standalone peripheral functions and are not MUXed.
§ For the HD[31:0]/AD[31:0] multiplexed pins pin numbers, see the Terminal Functions table.
