AD1885 CODEC - defining ADC & DAC sample rates

This AD1885 CODEC  is an old device but I need to change the ADC & DAC sample rates
in existing assembler code. 

I just can't find the explicit answers in the AD data sheet.
I want:-
left out at 9k6 Hz, right out at 48kHz ..... left in at 9k6 Hz, right in at 48kHz
and as an alternative:-
left out and right out at 9k6 Hz ....... left in at 9k6 Hz, right in at 48kHz
in the dm(tx_buf + COMMAND_DATA_SLOT)

Would be very grateful if you can either point me to the documentation that covers this
OR if you could supply the answers. 
cheers, Peter
