The SIOF_SYNC is a frame synchronous signal. Depending on the transfer mode, it has the
following two functions.
• Synchronous pulse: 1-bit-width pulse indicating the start of the frame
• L/R: 1/2-frame-width pulse indicating the left-channel stereo data (L) in high level and the
Figure 22.3 shows the SIOF_SYNC synchronization timing.
