In Short Frame Sync, the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is always one
clock cycle long.
Figure 5: Short Frame Sync (Shown with 16-bit Sample)
As with Long Frame Sync, BT830 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the
rising edge. PCM_OUT is configurable as high impedance on the falling edge of PCM_CLK in the LSB position or on
the rising edge.
8.4.4 Multi-Slot Operation
More than 1 SCO connection over the PCM interface is supported using multiple slots. Up to 3 SCO connections are
carried over any of the first 4 slots.
