Abstract: The present disclosure discloses a communication method for a slave device connected to a master device via an I2C bus. The method includes detecting the condition of a byte end flag when the slave device is in a transmission mode, and clearing the byte end flag to stop transmitting data to the master device as the slave device is in the transmission mode when the byte end flag is detected to be in a first condition. The first condition indicates all data requested by the master device has been transmitted by the slave device. The present disclosure further discloses a slave device using the above-mentioned communication method. When the slave device is in the transmission mode, it is unnecessary to switch the operation mode of the slave device to stop the slave device from continuing transmitting data when the last byte of data has been transmitted.
