Figure 25: Short Frame Sync (Shown with 16-bit Sample)
As with Long Frame Sync, WT11i samples PCM_IN on the falling edge of PCM_CLK and transmits
PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of
PCM_CLK in the LSB position or on the rising edge.
8.4 Multi-slot Operation
More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO
connections can be carried over any of the first four slots.

8.5 GCI Interface
WT11i is compatible with the GCI, a standard synchronous 2B+D ISDN timing interface. The two 64kbits/s B
channels can be accessed when this mode is configured.
