Rising edge outputs and falling edge inputs shown. Refer to
RINDO/TINDO programmed high or low on a per-time slot basis (SBCn; addr 0E0-0FF).
TSYNC/RSYNC represents frame (TFSYNC/RFSYNC) and multiframe (TMSYNC/RMSYNC) offset.
Multiple offset values shown for illustration, refer to OFFSET controls (addr 0D2-0D3, 0D5-0D6).
