Use MAX9867 with 8bit resolution

Question

I am writing an I2S driver for the MAX78000 MCU and the peripheral allows for 8bit, 16bit, 24bit and 32bit resolution. I am testing the driver with the MAX9867 and I noticed that when supplying the codec with a clock signal where BCLK=16*LRCLK (for 8bit stereo) the output of the codec remains 0. Is this the expected behaviour when trying to use the MAX9867 to convert into a 8bit signal? Can the codec only be used for 16bit resolution or is there a way to use with 8bit?

The MAX9867 must have a minimum of 16 bits per channel. As you mentioned in another comment, you can select which bits to use in the decoding device.)
