(ADV7611)About I2S freerun


I have some question about ADV7611.

(1) Is the purpose of setting up the I2S free run mode in ADI described on the data sheet?
If not, could you please tell me purpose of providing I2S free run mode?

(2) Could you please point out if the following flow is not recognized correctly?
・ If HDMI is not connected and set to free run mode, it operates in I2S free run mode.
・ When the HDMI connection is established, it synchronizes with the I2S communication speed of the connected device.
・ I2S communication speed is maintained even if HDMI is removed.
・ If the HDMI is not connected when the power is turned off or reset, it will operate again in free run mode.

Best regards
