Figure 15: Long Frame Sync (Shown with 8-bit Companded Sample)
BlueCore6-ROM (QFN) 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.
8.1.3 Short Frame Sync
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 16: Short Frame Sync (Shown with 16-bit Sample)
As with Long Frame Sync, BlueCore6-ROM (QFN) 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.
8.1.4 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.
