An ECU executes a program including the steps of: setting a first throttle opening degree (S100), setting a low gear torque LTE based on an engine torque map for low gear having the first throttle opening degree and an engine speed (rpm) as parameters (S200), setting a high gear torque HTE based on an engine torque map for high gear having the first throttle opening degree and the engine speed as parameters (S300), setting a target engine torque TTE by combining the low gear torque LTE and the high gear torque HTE by using a correction ratio KGR determined by a gear step (S400), and controlling the engine to produce a required torque set by using the target engine torque TTE (S700). In this way a torque can be obtained in accordance with the engine speed.

A data transfer control device including: a link controller which analyzes a packet received through a serial bus and generates a packet to be transmitted through the serial bus; an interface circuit which performs interface processing between the data transfer control device and a display driver connected to the data transfer control device through an interface bus; and a signal detection circuit which detects a vertical synchronization signal VCIN used for indicating a non-display period of a display panel and outputs a detection signal VDET. When the link controller has received a read request packet which requests reading of status of the VCIN, the link controller waits for the VDET to be output, and performs processing of transmitting a response packet through the serial bus on condition that the VDET has been output.

A data transfer control device includes a transceiver which receives a request packet from a partner device connected with the serial bus, and a link controller which analyzes the received request packet. The received request packet includes a response request field for informing whether or not to perform handshake transfer using an acknowledge packet. The link controller directs transmission of an acknowledge packet for the request packet when a response request value indicating that response is requested has been set in the response request field of the received request packet, and does not direct transmission of an acknowledge packet for the request packet when a response request value indicating that response is not requested has been set in the response request field.

In a bi-level displaying device, dither signal trains Y.sub.0 to Y.sub.15 for displaying half tone levels are generated from signal trains for basic tone levels X.sub.0 to X.sub.16 and from a 1/2 dither pattern constituted by the same numbers of dots having different threshold values. Dither signal trains Z.sub.0 Z.sub.31 for displaying unequally divided intermediate tone levels are generated by the basic trains X.sub.0 to X.sub.16 from a 1/4 dither pattern and a 3/4 dither pattern which are associated with unequal numbers dots having the different threshold values. Since the unequally divided intermediate tone levels can be displayed easily, it becomes possible to get natural intermediate tone levels. A dither pattern having a reversed pattern is adopted so that twice the number of intermediate tone levels can be displayed. Hence, a total of 64 tone levels can be displayed to produce images with fine detail and high resolution.
