Host-Port bus width user-configurable at device reset via a 10-kΩ resistor pullup/pulldown
resistor on the HD5 pin:
HD5 pin = 0: HPI operates as an HPI16.
(HPI bus is 16 bits wide. HD[15:0] pins are used and the remaining HD[31:16] pins are
reserved pins in the high-impedance state.)
I/O/Z
HD5 pin = 1: HPI operates as an HPI32.
(HPI bus is 32 bits wide. All HD[31:0] pins are used for host-port operations.)

The C6414T device does not support the PCI peripheral; therefore, the HPI peripheral pins are
standalone peripheral functions, not muxed.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-kΩ resistor should be used.)
For the C6415T and C6416T devices, these pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
The C6414T device does not support the PCI or UTOPIA peripherals; therefore, these muxed peripheral pins are standalone peripheral functions
for this device.
