摘要： A clock data recovery (CDR) circuit is provided with a circuit that updates a locked oscillation frequency, with a small loop gain, after phase lock based on a phase-locked loop circuit for a frequency-locked frequency is completed by a frequency-locked loop circuit or during a phase lock operation. Since the locked oscillation frequency is updated with a small loop gain, it is possible to correct a fluctuation in a frequency of an oscillation circuit in the frequency-locked loop circuit without oscillating a phase-locked loop undesirably even during a phase lock operation.

摘要： A display device is arranged so as to be able to conduct a touch detection action for sensing a region where a touch operation on a touch panel has been performed, to stop the touch detection action in the touch panel, and to specify a touch-detection-stop region. The display device includes an image-display-direction register. A processor writes parameters designating an image-display direction into the image-display-direction register based on a result of detection by a tilt detector. On condition that parameters stored in the image-display-direction register have been changed, the display device changes the touch-detection-stop region based on the parameters. The above function is mounted on a semiconductor integrated circuit device included in the display device.

摘要： The driver IC includes: a control circuit operable to perform control for creating the timing of detection by a touch panel in a non-display drive period during which the action of a drive circuit remains stopped, and for creating a display drive period during which the drive circuit drives the display panel, and the non-display drive period; and a data RAM operable to hold display data of more than one display line, but smaller than one display frame in capacity. The control circuit performs control for alternately creating the display and non-display drive periods by repeating a memory-addressing operation for writing display data supplied from outside into the RAM and reading the display data from the RAM at a speed faster than the writing speed to provide the read data to the drive circuit two or more times in a period of one display frame according to a wraparound method.
