DESCRIPTION
I/O/Z
Host-port data (I/O/Z) (default) (C64x) or PCI data-address bus (I/O/Z) (C6415 and C6416)
AS HPI data bus (PCIPEN pin = 0):
Used for transfer of data, address, and control .
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.)
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.)
As PCI data-address bus (PCI_EN pin = 1) (C6415 and C6416 devices only):
Used for transfer of data and address
The C6414 device does not support the PCI peripheral; therefore, the HPI peripheral pins
are stand alone peripheral functions, not MUXed.
I/O/Z
O
I/O/Z
I
O/Z
PCI command/byte enable 0 (I/O/Z). When PCI is disabled (PCI_EN = 0), this pin is
tied–off. For the C6414 device this pin is “Reserved (leave unconnected, do not connect to
power or ground).”
PCI serial interface chip select (O). When PCI is disabled (PCI_EN = 0), this pin is tied–off.
IPD For the C6414 device this pin is “Reserved (leave unconnected, do not connect to power or
ground).”
IPD McBSP2 transmit clock (I/O/Z) [default] or PCI serial interface clock (O).
IPU
McBSP2 receive data (I) [default] or PCI serial interface data in (I). In PCI mode, this pin is
connected to the output data pin of the serial PROM.
IPU
McBSP2 transmit data (O/Z) [default] or PCI serial interface data out (O). In PCI mode, this
pin is connected to the input data pin of the serial PROM.
