| description | The semiconductor integrated circuit device has: more than one analog port; an A/D conversion part operable to execute an A/D conversion process for converting an analog signal taken in through each analog port into a digital signal for each preset virtual channel; and an A/D conversion control part operable to control an action of the A/D conversion part. The A/D conversion control part includes: virtual channel registers on which correspondence between the virtual channel and the analog port can be set; and a scan-group-forming register on which a start position of a scan group and an end position thereof can be set. The A/D conversion control part controls the A/D conversion part to successively execute an A/D conversion process on a plurality of virtual channels from a virtual channel associated with the start pointer to a virtual channel associated with the end pointer. |
