Example 2: Only the first 2 bytes are transferred to the STA310 because the number of slots is 20 (16 + 4). SIN
and LRCLKIN are sampled on the falling edge of DSTR. The data is in delayed mode.
The register configuration is SIN_SETUP=3 and CAN_SETUP = DelayMode + LeftFirstChannel + FallingStrobe
+ AllSlot = 1 + 2 + 4 + 8 = 15.
This mode is a specific mode where only the first 16 data bits are transferred. The remaining bits are discarded.
The register configuration is SIN_SETUP = 3 and CAN_SETUP = DelayMode + FallingStrobe = 1 + 4 = 5.
4.4.1.3 SPDIF Input
A true SPDIF Input SPDIF (PCM audio samples) or IEC-61937 (compressed data) is selectable as a main serial
input.
4.4.1.4 Autodetected formats
