bdel0
Informs if the frame synch
(SYNC0)
is for a delayed frame of
non delayed frame
When bdel0 = 0,
the frame sync signal is aligned with the first
bit of the timeslot
When bdal0 = 1,
the frame sync is present one bit before the
first bit of the first timeslot.
[03]
Wb0
This bit informs if the PCM synchro
(SYNC0)
must be in
wideband type (one additional pulse at the middle of the frame)
When Wb0 = 0,
the PCM carries narrowband data. Only one
pulse is required for the framesync (generally every 125µS).
When Wb0 = 1,
the PCM carries wideband data. Two pulses
are required for the framesync (generally every 62.5µs)

M/S
When M/S = 0,
the device is slave for the SYNC0
When M/S = 1,
the device is master for SYNC0.
If the device is slave, it must be slave for the clock.
