Claim Text:
1. A semiconductor integrated circuit device which can be incorporated in a display device incorporated in an information technology device including a processor to be connected with a tilt detector for detecting a tilt, and having a display panel and a touch panel superposed on the display panel, and which is arranged to touch operation on the touch panel has been performed, and arranged to be able to designate a touch-detection-stop region to stop the touch detection action in the touch panel, the semiconductor integrated circuit device, comprising: an image-display-direction register arranged so that the processor can write parameters designating an image-display direction calculated based on a result of the detection by the tilt detector thereinto; and a conversion operation circuit for changing the touch-detection-stop region based on contents stored in the image-display-direction register on condition that the parameters stored in the image-display-direction register have been changed, wherein the touch panel includes a plurality of touch-drive lines, and a plurality of touch-sense lines intersecting with the plurality of touch-drive lines, the semiconductor integrated circuit device further comprising: a plurality of touch-drive circuits for driving the plurality of touch-drive lines respectively; a plurality of touch-sense circuits connected with the plurality of touch-sense lines respectively; a touch-drive-enable register; and a touch-sense enable register, the semiconductor integrated circuit device, arranged to be able to perform control for individually stopping the plurality of touch-drive circuits from working based on respective values set on the touch-drive-enable register respectively, and arranged to be able to perform control for individually stopping the plurality of touch-sense circuits from working based on respective values set on the touch-sense enable register.
