FAQ
How does a user determine which is the received I²C address if two or more than two I²C addresses are set to be received in Slave mode? Issue Date：2016-06-02
After receiving a preset I2C address and R/W bit, the I2C controller generates an interrupt, and the I2C status is changed to 0x60 or 0xA8. At this time, the received I2C address and R/W bit would be saved in the I²C register. Before clearing the 2C interrupt flag, a user could read the I2C data register to determine the received I2C address.
