indeed, we still don't have a description of how
this signal works. […]
Here is a description, but still don't know where to put
it:
The sa_bits byte contains the Sa bits in TS 0, if multi frame is used: bit 7 = Sa8, bit 6
= Sa7, bit 5 = Sa5, bit 4 = Sa4, bit 3 = Sa64, bit 2 = Sa63, bit 1 = Sa62, bit 0 = Sa61.
The sa_bits byte contains the Sa bits in TS 0, if double frame is used: bit 7 = Sa8, bit 6
= Sa7, bit 5 = Sa5, bit 4 = Sa4, bit 0 = Sa6.
The received Sa bits are reported whenever they change (and are stable for some frames,
depending on the implementation).
Before any report, all Sa bits are assumed to be set to 1.
Setting sa_bits byte will change the transmitted Sa bits on TS0.
Before setting them, all Sa bits are transmitted as 1.
