20.1 CHANNEL INTERLEAVE
In channel interleave mode data is output to the PCM Data Out bus one channel at a time from each of the
connected SCTs until all channels of frame n from all each SCT has been place on the bus. This mode
can be used even when the connected SCTs are operating asynchronous to each other. The elastic stores
will manage slip conditions. See Figure 21-13 for details.
20.2 FRAME INTERLEAVE
In frame interleave mode data is output to the PCM Data Out bus one frame at a time from each of the
connected SCTs. This mode is used only when all connected SCTs are synchronous. In this mode, slip
conditions are not allowed. See Figure 21-14 for details.

Figure 21-1 RECEIVE SIDE D4 TIMING
Notes:
1. RSYNC in the frame mode (RCR2.4 = 0) and double-wide frame sync is not enabled (RCR2.5 = 0)
2. RSYNC in the frame mode (RCR2.4 = 0) and double-wide frame sync is enabled (RCR2.5 = 1)
3. RSYNC in the multiframe mode (RCR2.4 = 1)
4. RLINK data (Fs - bits) is updated one bit prior to even frames and held for two frames
5. RLINK and RLCLK are not synchronous with RSYNC when the receive side elastic store is enabled
