Left and Right justified mode are computed using the same formula as DSP_A and DSP_B mode. Which is wrong and the user manual explicitly says: LRCK_PERDIOD: PCM Mode: Number of BCLKs within (Left + Right) channel width. I2S/Left-Justified/Right-Justified Mode: Number of BCLKs within each individual channel width(Left or Right) Fix this by using the same formula as the I2S mode.
