Questions answered in these manuals
How is the AD74111 codec reset?
The codec is reset using Flag 0 to generate a reset signal, which must meet specific timing requirements (tRES, tRS and tRH) for 3072 MCLK periods.
What are the two modes of operation for the AD74111 codec?
The codec operates in Mixed mode (default, allows register configuration) and Data mode (only data transmission).
What sample rate range does the AD74111 support?
It supports sample rates from 8 kHz to 48 kHz.
