For the remainder of this document, the PCI7x21 controller refers to the PCI7621 and PCI7421 controllers, and the PCI7x11 controller refers to the PCI7611 and PCI7411 controllers.

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, 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.

The PCI7x21/PCI7x11 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.

The PCI7x21/PCI7x11 controller also has a three-pin serial interface compatible with the Texas Instruments TPS2228 (default), TPS2226, TPS2224, and TPS2223A power switches. All four power switches provide power to the CardBus socket(s) on the PCI7x21/PCI7x11 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.
