We are thinking of a system ADV7511 and ADV7513 ,
SOC (RGB 6 Bit ) -> ADV751x ( Convert RGB bit to HDMI) -> HDMI connector -> SOC (Plan to throw 2LSB and output )
1. When input RGB is 6bit , by pulling the 2 LSB to GND will this be taken as 8 bit input mode .
2. Input format : Normal, are the 2 LSB od RGB as follows
R[1:0] ＝ Data[17:16]
G[1:0] ＝ Data[9:8]
B[1:0] ＝ Data[1:0]
3.When we are not using the Audio can we just GND the Audio related pins .
With best regards and wishes
