I have a question about SD Closed Captioning assignments of ADV7392.
According to FCC Code of Federal Regulations（CFR Title 47 Section 15.119 and EIA-608,
Closed Captioning data 8bit indicates 1 character.
ADV7392 has 4bytes SD closed captioning registers (Subaddress 0x91 to Subaddress 0x94).
Could you tell me how we should assign the registers.
May we set the binary data we want to display to the registers?
Are there any sequence which it should be careful of or any preference?
