PROBLEM TO BE SOLVED: To provide a semiconductor device and a communication control method therefor that can control a plurality of channels with a single control part and without increasing the number of control parts. SOLUTION: While the bus control part 21 having a master channel MC2 and a slave channel SC2 and capable of driving only either the master channel MC2 or the slave channel SC2 drives the master channel MC2, the single bus control part 21, when notified by a start condition detection circuit 16 that a start condition SA2 has occurred in the slave channel SC2, can suspend the drive of the master channel MC2 and drive the slave channel SC2 to control the two master channel MC2 and slave channel SC2 without an increase in the number of bus control parts 21.
