Abstract
A data length detection device for detecting the byte length of received data in accordance with High Level Data Link Control Procedure is disclosed. When the byte length of an information field included in the received data, for example, is detected, initial data determined based on the byte length is generated from initial data generation circuit. A counting device, after being initialized by the initial data, starts counting operation in response to detection of a start flag. When a stop flat is detected, the counting device stops the counting operation, and the data counted at the time represents the byte length of the information field. Since an adder/subtracter is not necessary to detect the byte length, time required for the detection can be shortened.
