NOTE(S):
1. TSYNC/RSYNC represents frame (TFSYNC/RFSYNC) and multiframe (TMSYNC/RMSYNC) offset.
2. RINDO/TINDO programmed high or low on a per-time slot basis (SBCn; addr 0E0-0FF).
3. Multiple offset values shown for illustration, refer to OFFSET controls (addr 0D2-0D3, 0D5-0D6).
4. Rising edge outputs and falling edge inputs shown. Refer to
5. Transmit ABCD signalling on TSIGI is sampled only during low nibble.
6. Received ABCD signalling on RSIGO is repeated in both high and low nibbles.
7. X2CLK control bit located in SBI_CR (addr 0D0).
