Patent number: 9286250Abstract: There is a need to cause a delay to occur less frequently than the related art during processing of an input signal in need of relatively fast processing. In a semiconductor device, a conversion portion includes first channels and second channels and A/D converts a signal input to a selected channel. A signal input to the first channel requires faster processing than a signal input to the second channel. The conversion portion receives a scan conversion instruction from a central processing unit, sequentially selects the input channels in a specified selection order, and successively performs A/D conversion. In this case, the conversion portion notifies a peripheral circuit of completion of A/D conversion after completion of A/D conversion on signals input to the first channels and before completion of A/D conversion on input signals input to all input channels.Type: GrantFiled: July 13, 2015Date of Patent: March 15, 2016Assignee: Renesas Electronics CorporationInventors: Daijiro Harada, Takashi Utsumi
