1-1 PCI445X Device This implementation guide assists platform hardware developers designing with the PCI445X dual socket PC card and 1394 open host controller interface (OHCI) link layer controller (LLC). The PCI445X designation refers to any device in the PCI445X family , for example, the PCI4450 or PCI4451 device. The document includes an overvie[...]

System Features Selection 1-3 PCI445X Device 1.1 System Features Selection This section explains selectable system features. Feature selection is required for GPIO and MFUNC terminal assignments and PCI445X register initialization. Detailed system implementation methods are described in the following sections. All functions cannot necessarily be us[...]

System Features Selection 1-4 automatically assigned on the dedicated SDA and SCL terminals. A pullup resistor (typically 10 k Ω) must be added on SDA and SCL when using an EEPROM. The value of the pullup resistor can vary for dif ferent EEPROMs. Refer to the EEPROM data sheet or contact the manufacturer for the recommended pullup resistor value.[...]

System Features Selection 1-5 PCI445X Device 1.1.10 Socket Activity LEDs Socket activity signals can be assigned on MFUNC4 (slot 1), MFUNC3 (slot 2), MFUNC5 (OHCI_LED), MFUNC6 (OHCI_LED), and MFUNC7 (OHCI_LED). 1.1.1 1 MFUNC7–MFUNC0 T erminal Assignments After selecting required functions for the system, multifunction terminals MFUNC7–MFUNC0 ar[...]

System Features Selection 1-6 1.1.12.3 Asynchronous CSC Interrupt Generation The ASYNC_CSC bit (diagnostic register , PCI offset 93h, bit 0) controls the CSC interrupt signaling method. If this bit is set to 0, then CSC is generated synchronously to PCLK (recommended). By default this bit is set to 1, which is the asynchronous mode. 1.1.12.4 CardBu[...]

System Features Selection 1-7 PCI445X Device CCLK can be slowed down rather than stopped by CCLKRUN . If CCLKRUN is set, the CLKCTRLEN (CardBus socket 20h, bit 16) and CLKCTR (CardBus socket 20h, bit 0) bits are both set to 1. The clock is slowed down to 1/16. In this mode the PCI clock is not allowed to stop. 1.1.12.9 SMI A PC card power change ev[...]

System Implementation 1-8 1.2 System Implementation This section describes signal connection for each interface, PCI bus, PC card interface, I 2 C interface, P 2 C interface, ZV interface, interrupt interface (parallel and serial), miscellaneous signals, and the PHY -Link interface. It also explains pullup/pulldown resistor requirements. 1.2.1 Clam[...]

System Implementation 1-9 PCI445X Device IDSEL, there is no alternative. If another AD line is to be used for IDSEL, then the system designer must leave the pullup off LA TCH and use MFUNC7 to route IDSEL. Also, if AD23 is used, then the resistive coupling should not be used. Refer to the Implementation Note: System Generation of IDSEL in the PCI L[...]

System Implementation 1-10 1.2.3 PC Card Interface The PC Card interface has two modes: the 16-bit interface mode and the CardBus 32-bit interface mode.  Damping resistor on CCLK terminal A series-damping resistor is recommended on the CCLK signal. The damping resistor is system dependent. If line impedance is in the 60 – 90- Ω range, a 47- [...]
