... Primary Frames. Hence, no Primary Frames are dropped. On Primary Frame transmits (DSP to Si3000), the Si3000 treats the LSB (16th bit flag to request a Secondary Frame. Set the primary frame LSB = 1 to request a secondary frame; otherwise, set the primary frame LSB = 0. Therefore, out of 16-bits of transmit data on SDI, only 15-bits represent actual audio data ...
