Short Frame Sync
In Short Frame Sync, the falling edge of BT_PCM_SYNC_P indicates the start of the PCM word.
BT_PCM_SYNC_P is always one clock cycle long.
Figure 11: Short Frame Sync (Shown with 16-bit Sample)
Like with Long Frame Sync, NEMO samples BT_PCM_RXD_P on the falling edge of
BT_PCM_CLK_P and transmits BT_PCM_TXD_P on the rising edge. BT_PCM_TXD_P maybe
configured to be high impedance on the falling edge of BT_PCM_CLK_P in the LSB position or on
the rising edge.
