to set Closed Caption Data
Sub Address 0x26
Sub Address 0x27
Note) Closed Caption Data is written in order of 0x26 and then 0x27.
When the second byte (0x27) of Closed Caption Data is written, the AK8825 interprets that Data has been up-dated and it
encodes the Data on the next Video Line.
Null Codes are automatically output on those, not-data-updated lines.
It is assumed that Parity bit of each Byte Data is added by the Host side.
