Data processor and data table update method

摘要

An interface controller is designed to separately define the first control information to be supplied to the first latch means for controlling an operation of an interface-controlled device connected to the same controller and the second control information to be supplied to the second latch means for controlling an interface operation with the interface-controlled device, in a form of a pair of the first and second information. When there is an addition or a change in a command defined for the interface-controlled device, as for a command transmission to the interface-controlled device and as for an interface control operation of the interface controller itself, both the control information can be independently amended to cope with the addition or the change.
