The SIOFSYNC 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 21.3 shows the SIOFSYNC synchronization timing.
