Abstract
A frame synchronous circuit operable in a dedicated short-range communication system, applicable to several modulation schemes, includes a UW detector for detecting a UW word from received data, an operation setting register group for specifying the operations of an on-board unit, a synchronous manager for controlling synchronization, an unlimited synchronization continuation register for maintaining the unlimited continuation of the synchronization, and an FCMC data analyzer for analyzing FCMC data. The operation setting register group can control synchronization by using not only operational information obtained from the FCMC data but also another operational information retrieved from an input device such as a CPU or terminal connected to the on-board unit. Consequently, debug and test operations can be performed without receiving any FCMC data.
