AUX Port Digital Interface Formats
These serial data lines are used when supporting the TDM Mode of operation with an external ADC or
S/PDIF receiver attached. The AUX serial port operates only as a clock master. The AUX_SCLK will operate
at 64xFs, where Fs is equal to the ADC sample rate (FS on the TDM interface). If the AUX_SDIN signal is
not being used, it should be tied to AGND via a pull-down resistor.

and must be held valid for at least 1 SCLK period.
Note:
I/O Channel Allocation
Hardware Mode
The AUX port will only operate in the Left-Justified digital interface format and supports bit depths ranging
from 16 to 24 bits (see
AUX_SCLK).
Software Mode
The AUX port will operate in either the Left-Justified or I²S digital interface format with bit depths ranging
from 16 to 24 bits. Settings for the AUX port are made through the register
