adjusted until the data differs. This kind of operation is called arbitration (n = 0 to 2).

When several master devices simultaneously generate a start condition (when the IICCn.STTn bit is set to 1 before
When one of the master devices loses in arbitration, an arbitration loss flag (IICSn.ALDn bit) is set to 1 via the
Arbitration loss is detected based on the timing of the next interrupt request signal (INTIICn) (the eighth or ninth
