29.4.2 Serial Timing
SIOF_SYNC: 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
right-channel stereo data (R) in low level
Figure 29.3 shows the SIOF_SYNC synchronization timing.
