Description
Reserved.
Reserved.
INIT_DONE
Initialization Done: Initialization sequence has completed. This step
will complete after configuration complete (CFG_DONE).
Reserved.
CFG_DONE
Configuration Complete: Indicates automatic configuration has
completed. This step will complete prior to initialization complete
(INIT_DONE).
CFG_CKSUM
Configuration checksum status: Indicates result of Configuration
checksum during initialization. The device verifies the 2’s complement
checksum in the last 128 bytes of the EEPROM. A value of 1 indicates
the checksum passed.
Reserved.
Reserved.
AUDIO_TDM
Enable TDM Audio: Setting this bit to a 1 will enable TDM audio for
the I2S audio. Parallel I2S data on the I2S pins will be serialized onto
a single I2S_DA signal for sending over the serial link.
AUDIO_MODE
Audio Mode: Selects source for audio to be sent over the FPD-Link III
downstream link.
0 :Disabled.
1 : I2S audio from I2S pins.
Reserved.
TDM_2_PARALL EnableTDM to parallel I2S audio conversion: When this bit is set, the
EL
TDM to parallel I2S conversion is enabled. TDM audio data on the
I2S_DA pin will be split onto four I2S data signals.
