TSB timebase alignment is arbitrary.
TSB timebase slaved to system bus TMSYNC. TFSYNC aligns to
TMSYNC input.
TSB timebase is aligned to embedded framing on TPCMI. TPCMI
must be configured to line rate for this case.
TSB timebase is aligned to embedded framing on TNRZ data.
TMSYNC is unused. TPCMI may be configured for 1,544 kbps or a
multiple of 2,048 kbps.
