Abstract
An ASIC (Application Specific Integrated Circuit) cell implementation of an ADB (Apple Desktop Bus) bus controller with programmable timing value registers for the Apple Desktop Bus (ADB) has a system interface for connecting to a computer system including an address bus interface, a data bus interface, and a control bus interface, and has an ADB interface for connecting to an ADB peripheral bus. A control state machine within the ADB bus controller uses timing data from the programmable timing value registers to implement the Apple Desktop Bus data signaling and communications protocol on the ADB interface.
