The KL02 works in master mode.

The IIC communication is failed when there is EMC disturbance.

The IIC communication is still failed when the EMC disturbance disappears.

The BUSY bit in register I2C1_S is always 1.It cannot be changed to 0.

It is only OK after the CPU resets.

Is there any method to restore the communication without resetting CPU when the EMC disturbance disappears?
