Serial Data Strobe Signal and strobed Data Clock
For time slot oriented standard devices connected to the IOM-2 interface the SCOUT-
DX provides two independent data strobe signals SDS1 and SDS2. The SDS2 function
is shared with the RSTO function at pin RSTO/SDS2, therefore the SDS2 functionality
must be selected by setting the RSS bits in the MODE1 register to ’01’.
Instead of a data strobe signal a strobed IOM bit clock can be provided on pin SDS1 and
SDS2.
