In the slave mode, a serial bus interface circuit operates either in normal slave mode or in slave mode after
In the slave mode, the conditions of generating INTSBI interrupt request are follows:
A serial bus interface circuit changes to a slave mode if arbitration is lost in the master mode. And an
