Register 7 (Frame-Sync Delay Register)
The following command contains the frame-sync delay (FSD) register address and loads DS07
(MSB) – DS00 into the FSD register. The data byte (DS01 – DS00) determines the number of SCLKs
between FS and the delayed frame-sync signal, FSD. The minimum data value for this register is
decimal 18.
