Hello, I am using STM8S105 as an I2C slave.

A strange thing happens when I disable I2C_StretchClockCmd(DISBALE).

When the master asks for data, the first byte is always its slave address, followed by the TX buffer. When I enable clock stretching, then the data is written correctly (without Slave address)
