2.3.2.2
For time slot oriented standard devices at the IOM
provides two independent data strobe signals SDS1 and SDS2.
The two strobe signals can be generated with every 8-kHz-frame and are controlled by
the registers SDS1/2_CR. By programming the TSS bits and three enable bits
(ENS_TSS, ENS_TSS+1, ENS_TSS+3) a data strobe can be generated for the IOM
time slots TS, TS+1 and TS+3 (bit7,6) and the combinations of them.
The data strobes for TS and TS+1 are always 8 bits long (bit7 to bit0) whereas the data
strobe for TS+3 is always 2 bits long (bit7, bit6).
