[AD1938] clock type/word length for 8-channel AUX ADC mode

Hi

 

I'd like to set AD1938 to 8-channel AUX ADC mode, and connect an extra ADC to AD1938. See Figure15 in AD1938's datasheet.

The extra ADC support only 2-channel I2S clock (SCLK = 64LRCLK).

My question is: (1) what's the clock format generated by AD1938 on AUX port? I2S or TDM8?

(2) what's the word length for AUX ADC? does it support 24bit?

Thanks!
