I2C clock stretching

Does Kinetis I2C module support clock stretching? Slave Baud Rate Control function of I2C module is not what I need. My slave just needs to hold low SCL for indeterminate time.


I tried not to clear IICIF flag after master completed transfer of current byte until slave is ready, but that seems not to prevent I2C master to use bus before IICIF is cleared.


Can somebody help me with implementing clock stretching?:
