IICSn.STDn bit is set to 1), communication between the master devices is performed while the number of clocks is
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 the
When one of the master devices loses in arbitration, an arbitration loss flag (IICSn.ALDn bit) is set to 1 via the timing at
Arbitration loss is detected based on the timing of the next interrupt request signal (INTIICn) (the eighth or ninth clock,
