NO.
These pins are software-configurable.
To use these pins as GPIO pins, the
GPxEN bits in the GPIO Enable
Register and the GPxDIR bits in the
GPIO Direction Register must be
properly configured.

To use GP[15:9] as GPIO pins, the PCI
needs to be disabled (PCI_EN = 0), the
GPxEN bits in the GPIO Enable
Register and the GPxDIR bits in the
GPIO Direction Register must be
properly configured.

By default, McBSP1 is enabled upon
reset (UTOPIA is disabled).
To enable the UTOPIA peripheral, an
external pullup resistor (1 kΩ) must be
provided on the BEA11 pin (setting
UTOPIA_EN = 1 at reset).

§
For the C6415T and C6416T 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 C6414T device does not support the PCI and UTOPIA peripherals. These are the only multiplexed pins on the C6414T 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.
