40 / 119 page ![]() TMS320C6411 FIXEDPOINT DIGITAL SIGNAL PROCESSOR SPRS196H − MARCH 2002 − REVISED JULY 2004 40 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 Terminal Functions (Continued) SIGNAL TYPE† IPD/ ‡ DESCRIPTION NAME NO. TYPE† IPD/ IPU‡ DESCRIPTION HOST-PORT INTERFACE (HPI) or PERIPHERAL COMPONENT INTERCONNECT (PCI) (CONTINUED) HD14/AD14§ U1 HD13/AD13§ U3 Host-port data (I/O/Z) [default] or PCI data-address bus (I/O/Z) HD12/AD12§ U2 Host-port data (I/O/Z) [default] or PCI data-address bus (I/O/Z) HD11/AD11§ V4 As HPI data bus (PCI_EN pin = 0) Used for transfer of data, address, and control HD10/AD10§ V1 As HPI data bus (PCI_EN pin = 0) • Used for transfer of data, address, and control • Host-Port bus width (HPI_WIDTH) user-configurable at device reset via a 10-kΩ resistor HD9/AD9§ V3 • Host-Port bus width (HPI_WIDTH) user-configurable at device reset via a 10-kΩ resistor pullup/pulldown resistor on the HD5 pin: HD8/AD8§ V2 pullup/pulldown resistor on the HD5 pin: HD5 pin = 0: HPI operates as an HPI16. HD7/AD7§ W2 I/O/Z 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 HD6/AD6§ W4 I/O/Z (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/AD5§ Y1 reserved pins in the high-impedance state.) HD5 pin = 1: HPI operates as an HPI32. HD4/AD4§ Y3 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.) HD3/AD3§ Y2 (HPI bus is 32 bits wide. All HD[31:0] pins are used for host-port operations.) HD2/AD2§ Y4 As PCI data-address bus (PCI_EN pin = 1) Used for transfer of data and address HD1/AD1§ AA1 • Used for transfer of data and address HD0/AD0§ AA3 PCBE0§ W3 I/O/Z PCI command/byte enable 0 (I/O/Z). When PCI is disabled (PCI_EN = 0), this pin is tied-off. XSP_CS AD1 O IPD PCI serial interface chip select (O). When PCI is disabled (PCI_EN = 0), this pin is tied-off. XSP_CLK AC2 I/O/Z IPD This pin has no function at default [default] or when PCI is enabled (PCI_EN = 1), this pin is the PCI serial interface clock (O). XSP_DI AB3 I IPU This pin has no function at default [default] or when PCI is enabled (PCI_EN = 1), this pin is the PCI serial interface data in (I). In PCI mode, this pin is connected to the output data pin of the serial PROM. XSP_DO AA2 O/Z IPU This pin has no function at default [default] or when PCI is enabled (PCI_EN = 1), this pin is the PCI serial interface data out (O). In PCI mode, this pin is connected to the input data pin of the serial PROM. GP15/PRST§ G3 General-purpose input/output (GPIO) 15 pin (I/O/Z) or PCI reset (I). No function at default. GP14/PCLK§ F2 GPIO 14 pin (I/O/Z) or PCI clock (I). No function at default. GP13/PINTA§ G4 GPIO 13 pin (I/O/Z) or PCI interrupt A (O/Z). No function at default. GP12/PGNT§ J3 I/O/Z GPIO 12 pin (I/O/Z) or PCI bus grant (I). No function at default. GP11/PREQ§ F1 I/O/Z GPIO 11 pin (I/O/Z) or PCI bus request (O/Z). No function at default. GP10/PCBE3§ L2 GPIO 10 pin (I/O/Z) or PCI command/byte enable 3 (I/O/Z). No function at default. GP9/PIDSEL§ M3 GPIO 9 pin (I/O/Z) or PCI initialization device select (I). No function at default. † 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-k Ω resistor should be used, unless otherwise noted.) § These pins are multiplexed pins.
