All card signals are internally buffered to allow hot insertion and removal without external buffering. The PCI6411

controller is register compatible with the Intel 82365SL-DF ExCA controller. The PCI6411 internal data path logic

allows the host to access 8-, 16-, and 32-bit cards using full 32-bit PCI cycles for maximum performance. Independent

buffering and a pipeline architecture provide an unsurpassed performance level with sustained bursting. The

PCI6411 controller can be programmed to accept posted writes to improve bus utilization.

Function 3 of the PCI6411 controller is a PCI-based Flash Media controller that supports Memory Stick, Memory

Stick-Pro, SmartMedia, XD, SD, and MMC cards. This function controls communication with these Flash Media cards

through a passive PC Card adapter or through a dedicated Flash Media socket. In addition, this function includes DMA

capabilities for improved Flash Media performance.

Function 4 of the PCI6411 controller is a PCI-based SD host controller that supports MMC, SD, and SDIO cards. This

function controls communication with these Flash Media cards through a passive PC Card adapter or through a

dedicated Flash Media socket. In addition, this function is compliant with the SD Host Controller Standard

Specification and includes both DMA capabilities and support for SD suspend/resume.

1.1.5

Multifunctional Terminals

Various implementation-specific functions and general-purpose inputs and outputs are provided through eight

multifunction terminals. These terminals present a system with options in PC/PCI DMA, PCI LOCK, serial and parallel

interrupts, PC Card activity indicator LEDs, flash media LEDs, and other platform-specific signals. PCI complaint

general-purpose events may be programmed and controlled through the multifunction terminals, and an

ACPI-compliant programming interface is included for the general-purpose inputs and outputs.

1.1.6

PCI Bus Power Management

The PCI6x21/PCI6x11 controller is compliant with the latest PCI Bus Power Management Specification, and provides

several low-power modes, which enable the host power system to further reduce power consumption.

1.1.7

Power Switch Interface

The PCI6x21/PCI6x11 controller also has a three-pin serial interface compatible with the Texas Instruments TPS2228

(default), TPS2226, TPS2224, and TPS2223A power switches. All three power switches provide power to the

CardBus socket(s) on the PCI6x21/PCI6x11 controller. The power to each dedicated socket is controlled through

separate power control pins. Each of these power control pins can be connected to an external 3.3-V power switch.

1.2
