How to make the KL26 MCU BCP bit work?

   When the BCP bit of I2S register TCR2 of KL26 MCU is set, it is expected that "Bit clock is active low with drive outputs on falling edge and sample inputs on rising edge". But I found that doesn't work. It menas the I2S SCLK doesn't change when the BCP bit is set or not.

   Plear help to confirm how to make the BCP work.
