The 192 available bits during a 80 kHz period (related to the 15.36 MHz clock) are
divided into the 9 slots of which 8 slots are 21 bits long used for data transmission.
The status on SDR is synchronized to SDX. Each time slot on SDR carries the
corresponding LD bit during the last 20 bits of the slot.

3.4.2
The 128 available bits during a 120 kHz period (related to the 15.36 MHz clock) are
divided into 9 slots of which 8 slots are 13 bits long used for data transmission. The
status on SDR is synchronized to SDX. Each time slot on SDR carries the corresponding
LD bit during the last 12 bits of the slot.

TD 2
First bit of the time slots with transmission data. For synchronization and bit
allocation on SDX and SDR, SY is set to ONE.
Reserved bit. Reserved bits are currently not defined and shall be set to
ZERO. Some of these bits may be used for test purposes or can be assigned
a function in later versions.
