6.5.4 ADC DIGITAL INTERFACE FORMAT (ADC_DIF[2:0])
Default = 110
Function:
These bits select the digital interface format used for the ADC serial port. The required relationship be-
tween the Left/Right clock, serial clock and serial data is defined by the Digital Interface Format and
the options are detailed in the section “CODEC Digital Interface Formats” on page 32. Refer to Table
9. “Serial Audio Interface Channel Allocations” on page 36.
NOTE: The ADC does not meet Quad-Speed Mode timing specifications in the TDM interface format.
