    • A peripheral interface system and apparatus including a pair of integrated circuits, referred to as a system adapter and a socket controller, use a communication protocol, referred to as a windowed-interchip-communication protocol, to interface peripherals, such as PCMCIA cards or infrared devices, and other subsystems having different formats with a CPU system bus. The system adapter communicates to a hard disk drive subsystem using the ATA communication standards to interface an ATA hard disk drive with the CPU system bus. Communication between the system adapter and the socket controller, which communicates with PCMCIA peripheral cards and IR peripherals, is accomplished using the windowed-interchip-communication protocol which may share hardware resources with other communication protocols. Communication between the system adapter and the hard disk drive and between the system adapter and the socket controller may be provided on the same chain of a standard 40 signal ribbon cable. Alternatively communication between an expansion board and a socket controller may be performed across a cable separate from the hard disk drives having a different signal line format. The system adapter may be included within a single interface expansion board which can be connected to the motherboard and CPU system bus or it can be directly connected or soldered to the motherboard and communicate with the socket controller and ATA hard disk drives using one or more busses.

    • An integrated automatic bus setting, sensing and switching interface unit is manufactured on board an integrated circuit to interface between the integrated circuit and the system bus. The interface unit can support a plurality of bus structures utilizing the same pins on the integrated circuit for different functions. Several modes of establishing an interface structure are available in the unit. An Address Strobe pin on the integrated circuit is used to automatically detect a signal level representative of the bus structure to be used. A code representative of the parameters of the bus structure is also stored in a configuration register for controlling the interface unit and configuring the pins on the integrated circuit for the specific bus structure to be used. The Basic Input Output System (BIOS) as its first operation stores the code in a register whose contents are then written to the configuration register of the integrated circuit for controlling and configuring the integrated circuit. A combination of these modes is also available.

    • An apparatus for providing register compatibility between integrated circuits having different register and interrupt configurations is designed to operate with software that was written for previous hardware. Versions of software written for previous hardware attempt non-native register accesses for which the integrated circuit is designed to emulate the non-native register set. Versions of software specifically written for the present hardware attempt native register accesses for which no emulation is necessary. In the preferred embodiment only one physical register set is included on the integrated circuit and a compatibility engine is used when a non-native register access is attempted. The compatibility engine is coupled between a bus interface unit and the physical register set and allows a user or system designer to address a register set of another integrated circuit having a different configuration than the physical register set. The compatibility engine converts the address and maps the data bits of the emulated register into registers within the physical register set. Alternatively, two sets of registers can be physically included on the integrated circuit. An interrupt compatibility circuit is also designed to operate in at least a first mode or a second mode. In the first mode the interrupt information is written to an appropriate register and then mapped into the appropriate bits of the physical register set. In the second mode the interrupt information is written directly to the appropriate register. In both the first and second modes, steering bits from the appropriate register are used to map system, management and wakeup interrupts to the appropriate interrupt pad where the interrupt request signal is then shaped.
