GP1EN = 0 (disabled)
GP2EN = 0 (disabled)
GP8EN = 0 (disabled)
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.
GPxEN = 1: GPx pin enabled
GPxDIR = 0: GPx pin is an input
GPxDIR = 1: GPx pin is an output

GPxEN = 0 (disabled)
PCI_EN = 0 (disabled)†
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.
GPxEN = 1: GPx pin enabled
GPxDIR = 0: GPx pin is an input
GPxDIR = 1: GPx pin is an output

UTOPIA_EN (BEA11) = 0
(disabled)†
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).

PCI_EN = 0 (disabled)†
By default, HPI is enabled upon reset
(PCI is disabled).
To enable the PCI peripheral an external
pullup resistor (1 kΩ) must be provided
on the PCI_EN pin (setting PCI_EN = 1
at reset).

† _{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.}
